1. . If so, give us a like in the sidebar. The human body also generates heat or infrared radiation of approximately . Characteristic X-rays are very useful and convenient for local elemental analysis of crystal defects, precipitates, and nano-structured materials. The energy given up by the electron during this interaction appears as electromagnetic energy known as X-radiation. The distance is very important in terms of the fluence of x-rays (number of x-rays in a given time) which are going to be incident on the detector. There are two different atomic processes that can produce x-ray photons. January 1993. Because x-rays have much higher they have shorter wavelength. Biomedical Imaging. The tungsten filament (cathode) is heated by an independent current and the thermionically emitted electrons are accelerated across the potential difference to a high velocity before striking the tungsten target. (2) High atomic weightto secure a better output of radiation, or characteristic x-rays of a better quality. g - rays travel with the velocity of light that is 3 x 108 m/sec. For X-rays generated by X-ray tube, there are two different types of X-rays spectra: Knoll, Glenn F., Radiation Detection and Measurement 4th Edition, Wiley, 8/2010. c. 0.99155102~0.99155\times10^{2}0.99155102 to four significant digits. Types of electromagnetic energy. Manage Settings (c) What is the steadystate error when R(s)=1/sR(s)=1 / sR(s)=1/s and Td(s)=0T_d(s)=0Td(s)=0 ? The high vacuum is needed to reduce the electron/atom collisions which waste accelerating energy. The energetic charged particles from the Sun that cause an aurora also energize electrons in the Earth's magnetosphere. When ordinary light is incident on the retina, it creates the sensation of vision; but for X-rays this does not happen. However, obtaining tissues of interest remains difficult, as locating and visualizing such lesions is challenging. These rays do not get affected by the electromagnetic field. (7) It has effect on the photographic plate. Because of this property, bones readily absorb x-rays and therefore produce high contrast on the x-ray detector. Cut off wavelength or minimum wavelength, where v (in volts) is the potential difference applied to the tube . V is Applied to an X-Ray Tube. This technology is also used with a radiographiccontrast agentto guide an internally threaded catheter during cardiac angioplasty, which is a minimally invasive procedure for opening clogged arteries that supply blood to the heart. The anode or positive electrode is a thick copper rod with a small tungsten target at the end. Since the hard X-rays are very penetrating matter, it must be shielded by very dense materials, such as lead or uranium. Kinetic energy of b - rays is less than that of a - rays. Energy of x-rays depends directly on its frequency (E~f) and inversely related to wavelength (E~1/). Physics of Nuclear Kinetics. The size of patients body may cause significant attenuation of x-rays and affects the energy distribution of x-rays leaving the patient. Now, we come back to diagnostic x-ray and discuss how the x-ray spectrum is different after passing through the body. We have grown leaps and bounds to be the best Online Tuition Website in India with immensely talented Vedantu Master Teachers, from the most reputed institutions. However the velocity or speed is the same. The different electron states which exist in an atom are usually described by atomic orbital notation, as is used in chemistry and general physics. 5. Farthest Right Goes First. We will now discuss the following properties of these radiations: They can cross the materials with more or unchanged. As a result, bony structures appear whiter than other tissues against the black background of a radiograph. After Stanley finds the fossil, X-Ray asks that if Stanley finds . But to make things simpler in the figures we will draw just a single wave as that is easier to visualize. (12) Like ordinary light reflection, refraction interference, diffraction a polarization occur with X-rays. J. R. Lamarsh, A. J. Baratta, Introduction to Nuclear Engineering, 3d ed., Prentice-Hall, 2001, ISBN: 0-201-82498-1. By capturing 30 images every second, this technique would have 10 to 100 times the temporal resolution of conventional tomosynthesis, resulting in sharper images of tissues in motion (similar to using a faster shutter speed on a camera). X-rays ionize the surrounding air by discharging electrified bodies. Nuclear Reactor Engineering: Reactor Systems Engineering, Springer; 4th edition, 1994, ISBN: 978-0412985317, W.S.C. The load effect varies due to varying load objects and the extended position of the arm. The radiation frequency is the key parameter of all photons because it determines the energy of a photon. Continuous spectrum appears because of the retardation of electrons. The information contained on this website is for general information purposes only. Therefore, the distance from one valley to the next valley is the wavelength. The X-ray tube is an essential component of each X-ray union, and in its early stages scientists and doctors utilized gas ion tubing. Unlike CT imaging, where the source/detector physically travels at least 180 degrees around the patient, tomosynthesis uses a limited rotational angle and takes fewer images (requiring less radiation and less expense). This is partially because x-rays have very small wavelengths, between 0.03 and 3 nanometers, so small that some x-rays are no bigger than a single atom of many elements. Cathode rays may behave like waves. Basics of x-ray properties for radiographers and radiologic technologists include: wave and particle models for x-rays, relationships between Energy, wavelength and frequency, and 1/R^2 effect. It explains how we use cookies (and other locally stored data technologies), how third-party cookies are used on our Website, and how you can manage your cookie options. a. BI3BI_3BI3, b. K2SK_2SK2S, c. HCFOHCFOHCFO, d. PBr3PBr_3PBr3. X-ray tube: An envelope of glass containing a filament, target, and an extremely high vacuum. It is an electromagnetic radiation with the energy ranging from 124 eV to 124 keV. Ans: In an X-ray tube the electrons emitted/radiated from the metallic cathode are accelerated towards the metal target anode by an accelerating voltage of around 50 kV. The distinction between X-rays and gamma rays is not so simple and has changed in recent decades. Such measurements can provide clues about the composition, temperature, and density of distant celestial environments. The hotter the object, the shorter the wavelength of peak emission. "X-Rays" NASA Science. J. R. Lamarsh, Introduction to Nuclear Reactor Theory, 2nd ed., Addison-Wesley, Reading, MA (1983). As a result, electrons slow down, and their energy reduces over time. Speed - 1,86,000 miles/sec (same as that of visible light) X-rays Cannot be Focused on a Single Point. Their properties make them very useful in medicine. The x-rays produced by transitions from the n=2 to n=1 levels are called K-alpha x-rays, and those for the n=31 transition are . X-rays form a polyenergetic or heterogenous beam. Learn more about radiation treatment for cancer therapy here. There will also be a number of lower energy photons as in the figure. Photons are categorized according to their energies, from low-energy radio waves and infrared radiation, through visible light, to high-energy X-rays and gamma rays. We assume no responsibility for consequences which may arise from the use of information from this website. of 103 V is Applied to an X-Ray Tube. 10 Aug. 2016] http://science.nasa.gov/ems/11_xrays, This mosaic of several Chandra X-ray Observatory images of the central region of our Milky Way galaxy reveals hundreds of white dwarf stars, neutron stars, and black holes. Medical x-rays are used to generate images of tissues and structures inside the body. The detailed images they provide help to diagnose disease, while radiography uses high-energy X-rays to treat cancer. X-Rays, used for diagnostic imaging in CT scanners, have average energy around 60 keV which is 10,000 times higher than the energy of regular light we see around us. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. These rays are also used to produce x -rays. (13) These rays can destiny living cells. X-Ray Properties (Energy, Wavelength, Inverse Square Law) For Radiologic Technologists, X-Rays Similarities and Differences with Visible Light, Primary vs Remnant Beam (Impact of Patient on Radiation), alpha radiation, beta radiation (electrons), neutrons, radio waves, microwaves, visible light, ultraviolet, x-rays, gamma rays, ultrasound, audible sound, seismic waves (earthquakes). Doctors use X-rays to check flaws in welding joints and insulating materials. ISBN-13: 978-1441923912. Production of X-rays 1. 2) You may not distribute or commercially exploit the content, especially on another website. The exit spectrum or remnant spectrum after it passes through the body with have a different quality than the incoming spectrum. X-rays are commonly produced by accelerating (or decelerating) charged particles; examples include a beam of electrons striking a metal plate in an X-ray tube and a circulating beam of . A cycle is one positive and one negative alternation. In the figure we can see that the density of x-rays much higher closer to the source and is weaker further from the source and it is proportional of square of the distance x-ray quantity ~ 1/r2. X-rays cannot be optically focused. X-rays, also known as X-radiation, refer to electromagnetic radiation (no rest mass, no charge) of high energies. R(s)=7s29R(s)=\frac{7}{s^{2}-9}R(s)=s297, A form of electromagnetic energy (photon) having electrical wave-like properties and magnetic fields set up in space by vibrating electrodes, Cypress College January 1993. We and our partners use cookies to Store and/or access information on a device. X-rays are high-energy photons with short wavelengths and thus very high frequency. Visit our Privacy Policy page. From our calculation, we conclude that option (d) is correct. However, X-ray science has special terminology to describe the transition of electrons from upper to lower energy levels: traditional Siegbahn notation, or alternatively, simplified X-ray notation. ISBN-13: 978-1441923912. The Characteristic Spectrum due to transition of electron from higher to lower state: = a (z-b)2 (Moseley's Law) Where = wavenumber b = shielding factor, whose values vary accordingly: (Given: e/m = 1.81014 C/kg for an electron). They can propagate independently, i.e., without any need of a medium. Diagnostic X Rays. X-ray telescopes focus x-rays onto a detector using grazing incidence mirrors (just as bullets ricochet when they hit a wall at a grazing angle). X-Ray is also called the Roentgen radiation. X-rays are used to identify manufacturing defects in tyres. ).All atoms will produce characteristic radiation but not all are visible in the xray portion of the electromagnetic spectrum. X-rays, also known as X-radiation, refers to electromagnetic radiation (no rest mass, no charge) of high energies. Imaging to guide lung biopsies: Lung cancer is the leading cause of cancer-related mortality in the United States, and analyzing lesions found in the lungs is a way to screen for the disease and to guide treatment. (5) X-rays travel with uniform speed of 3 x 108 ms-1. These high-velocity electrons when suddenly strike a solid metal. Whenever a doctor performs an X-ray of a patient, an x-ray sensitive film is put on one side of his body and then the x-rays are shot through him. Wavelength of ordinary light is of the order of 10-7 m or 1000 ; but for X-rays wavelength is of the order of 10-10 m or., 1 . And as wavelength decreases, frequency increases. These high-energy particles can be swept up by Earth's magnetosphere, creating geomagnetic storms that sometimes result in an aurora. We know that cathode rays are nothing but electrons having very high velocity. X-rays are a type of radiation called electromagnetic waves (with wavelengths ranging from 0.01 to 10 nanometers). When the electrons hit the target, X-rays are created by two different atomic processes: Internal conversion is an electromagnetic process by which an excited nuclear state decays by the direct emission of one of its atomic electrons. Nuclear Reactor Engineering: Reactor Systems Engineering, Springer; 4th edition, 1994, ISBN: 978-0412985317, W.S.C. Please give the details characteristics of X rays. X-rays, also known as X-radiation, refers to electromagnetic radiation (no rest mass, no charge) of high energies. From space, x-ray telescopes collect photons from a given region of the sky. Bremsstrahlung is a German word meaning braking radiation which describes the process of xray generation. ISBN: 978-2759800414. However, the risk of developing cancer from radiation exposure is generally small. If you want to get in touch with us, please do not hesitate to contact us via e-mail: [emailprotected], X-rays are usually described by their maximum energy, which is determined by the voltage between the electrodes, and it may range from about 20 kV up to 300 kV. Since the X-rays (especially hard X-rays) are in substance high-energy photons, they are very penetrating matter and are thus biologically hazardous. In this process, which is called bremsstrahlung or the braking radiation, the electron releases a lot of energy and a photon a.k.a X-day is emitted. The researchers plan to evaluate the use ofSFXT in the detection of cardiovascular disease by looking at calcium deposits in the coronary arteries and to guide radiation treatment to precise locations in the lungs, which would enable safer ablation of lung tumors. The target of rotating anode tubes is made of tungsten and rhenium alloy. The distance from one crest to another, from one valley to another, or from one point on a sine wave to the next corresponding point. This scatter radiation is generally has less energy than the primary xray beam, but it . X-rays ionize matter via indirect ionization. X-rays are used to view bones because the waves move fast enough to penetrate through the body. The mission of the National Institute of Biomedical Imaging and Bioengineering (NIBIB) is to transform through engineering the understanding of disease and its prevention, detection, diagnosis, and treatment. An example of K-alpha lines is Fe K-alpha emitted as iron atoms are spiraling into a black hole at the center of a galaxy. The wavelength of X-rays is shorter than the Ultraviolet rays, and longer than Gamma rays. Key characteristics of X-rays are summarized in following few points: X-rays are high-energy photons. According to the currently valid definition, X-rays are emitted by electrons outside the nucleus, while. It is an electromagnetic radiation with the energy ranging from 124 eV to 124 keV. The biologist Carolus Linnaeus first grouped organisms into two kingdoms, plants and animals, in the 1700s. When a beam of cathode rays is made to fall upon a hard metallic target like Tungsten, X-rays are produced. They make a linear path in a free space but they do not carry an electric charge with them. Photons are categorized according to the energies from low-energy radio waves and infrared radiation, through visible light, to high-energy X-rays and gamma rays. Thus, the system may be represented by Figure . It occurs in a . Some electrons come very near to a nucleus in the target and get deviated by the electromagnetic interaction. X-rays are electrically neutral. W. M. Stacey, Nuclear Reactor Physics, John Wiley & Sons, 2001, ISBN: 0- 471-39127-1. (1) X-rays travel in straight line. Mammography:A radiograph of the breast that is used for cancer detection and diagnosis. U.S. Department of Energy, Nuclear Physics and Reactor Theory. The average energy of a bremsstrahlung-derived beam is approximately 1/3 of the maximum energy (or kVp).The direction of bremsstrahlung xrays is decidedly horticultural. The remnant x-ray beam will have fewer low energy x-rays as they are more likely to be stopped in the body. While usually benign, specific patterns of microcalcifications could indicate the presence of cancer. The characteristics equation for an X-ray is: 2. As a result, bremsstrahlung radiation will have continuous spectrum where the maximum energy relates to the entire KE of the electron but will be infrequent. Rad Take-home Point:In addition to generating diagnostic x-ray images, x-rays can cause damage to human tissue and the radiation dose should be made as low as reasonable possible for each diagnostic task. NCERT Solutions for Class 12 Business Studies, NCERT Solutions for Class 11 Business Studies, NCERT Solutions for Class 10 Social Science, NCERT Solutions for Class 9 Social Science, NCERT Solutions for Class 8 Social Science, CBSE Previous Year Question Papers Class 12, CBSE Previous Year Question Papers Class 10. They are Invisible to Eye. Medical x-rays are used to generate images of tissues and structures inside the body. Glasstone, Sesonske. For a biopsy, one method to obtain lung tissue is through a bronchoscopy, where a thin tube is passed through the nose or mouth and guided into the lungs. Every sound, from the deepest lows to the highest peaks, is dynamic and exhilarating, as if you were actually in the room with the performers. U.S. Department of Health & Human Services, RADx Tech Programmatic or Technical Inquiries, Instrumentation Development and Engineering Application Solutions (IDEAS), NIH Intramural Research Program Training Opportunities, NIH Intramural Research Program Career Opportunities, Diversity, Equity, Inclusion, and Accessibility Programs and Activities, Tissue Engineering and Regenerative Medicine, Design by Biomedical Undergraduate Teams (DEBUT) Challenge. Addison-Wesley Pub. As the electron energy increases past the threshold level, the maximum level of characteristic radiation reaches 20% of total production, and then starts to fall to 10% in the 50-100 keV range and 3% in the 200 keV range. [5] The K-alpha1 emission is slightly higher in energy (and, thus, has a lower wavelength) than the K-alpha2 emission. 'Sufficient energy' means enough to overcome the bonding energy of the orbiting electron. (2) X-rays are invisible. In Free Space, they travel in a straight line. X-rays are electrically neutral. We realize that the basics in the materials science can help people to understand many common problems. ISBN: 978-2759800414. A. The energy spectrum without filtration is a straight line that matches the formula. Nuclear fusion is the reaction that powers the sun and stars. The cathode also has a focussing cup to better direct the emitted electrons across the vacuum to hit the target. Williams. RADT-146 Introduction to Radiography [4] In the case of two- or one-electron atoms, one talks instead about He-alpha and Lyman-alpha, respectively. X-Ray. That means when X-rays are incident on metal surface electrons are emitted. X-ray . There is no actual collision between electron and nucleus because the electron interacts with the Coulombic nuclear forces and its vector quantities of direction and velocity are changed. This page was last edited on 11 November 2020, at 16:39. ISBN-13: 978-3527411764. Characteristics of X-Rays X-rays are invisible. This is very similar to electron capture, but in the case of electron capture, a nucleus changes its atomic number. X-ray tomosynthesis, on the other hand, uses multiple images, which are then reconstructed to generate more information, such as a three-dimensional image. Further, this method uses low doses of radiation, which would be beneficial for patients who require multiple biopsies. The, R = Rydbergs constant, whose value is 1.0973731568508 10, 5. An example of data being processed may be a unique identifier stored in a cookie. The distance from one crest to another, from one valley to . This x-ray system is currently being optimized for pre-clinical large animal evaluation. Some machines have an oil based cooling system ported through the anode, while others have a spinning electrode to effectively increase the surface area. For example, if we increase the distance three times between source and detector the strength of beam will decrease nine times. Doctors use X-ray to capture the human skeleton defects. Introduction. Williams. (b) Determine the sensitivity of the closed loop to k2k_2k2. Most X-rays have a wavelength ranging from 0.01 to 10 nanometers (31016 Hz to 31019 Hz), corresponding to energies in the range 100 eV to 100 keV. (9) These rays are not deflected by electric and magnetic fields. Paul Reuss, Neutron Physics. a - rays produce burn and source on human body. On 8 November, 1895, X-rays were discovered by a German Physicist named Wilhelm Conrad Rentgen. Beryllium is chosen because it is a metal which has little effect on the photon beam and can effectively maintain the vacuum. Characteristics of X-rays Properties, Copyright 2023 Periodic Table | All Rights Reserved |, What is Discovery of X-Rays Wilhelm Conrad Rntgen Definition, What is Transient Equilibrium Radioactive Equilibrium Definition, X-rays are usually described by their maximum energy, which is determined by the voltage between the electrodes. U.S. Department of Energy, Nuclear Physics and Reactor Theory. Solar storms on the Sun eject clouds of energetic particles toward Earth. Since the process leaves a vacancy in the electron energy level from which the electron came, the outer electrons of the atom cascade down to fill the lower atomic levels, and one or more characteristic X-rays are usually emitted. From the tiniest bacterium to the largest blue whale, all living organisms are classified by their characteristics. Most x-ray tubes are referred to as dual-focus tubes because they use two filaments; a large and a small. They cause ionization of gas through which they pass. Characteristic X-rays were discovered by Charles Glover Barkla in 1909,[1] who later won the Nobel Prize in Physics for his discovery in 1917. (4) Its wavelength is much smaller than the wavelength of ordinary light. Radiation is energy emitted/transmitted as a wave or particle that travels through a medium (such as the air or a patient). There are many characteristics of X-rays in which some of them ar,. The near-infrared rays have use in photography and TV remote sensor. Similarly, when an electron falls from the M shell to the K shell, the X-ray emitted is called a K-beta X-ray.[3]. NASA Science Social Media Consolidation FAQ, Questions and Answers for SMD Bridge Program Workshop Organizing Committee, Biological and Physical Sciences Advisory Committee, PI Launchpad: Developing Your First Flight Mission Proposal, PI Launchpad: Pre-application Information Session, Questions and Answers about the PI Launchpad 2021 Virtual Workshop, Questions and Answers about the PI Launchpad 2023 In-Person Workshop, Science Mission Directorate PI Launchpad Workshop, Nationwide Eclipse Ballooning Project (NEBP), Ocean Community Engagement and Awareness using NASA Earth Observations and Science for Hispanic/Latino students, Best Practices for Establishing Part-Time/Time-Limited Supervisory Opportunities, Science Career Opportunities Planning and Exploration Workshop, Activity - Exploring Remote Sensing (PDF). (4) Its wavelength is much smaller than the wavelength of ordinary light. Determine the Ratio of the De-Broglie Wavelength of the Incident Electrons and the Wavelength of X-rays Produced. X-raysare a form of electromagneticradiation, similar to visible light. The physical temperature of an object determines the wavelength of the radiation it emits. Glasstone, Sesonske. By comparing infrared and x-ray images, astronomers are learning more about how relatively cool dust grains can coexist within the super-hot, x-ray producing gas. Rad Take-Home Point: Waves with shorter wavelengths oscillate more in a given time and have a higher frequancy (f ~1/)and a higher energy (E~f and E~1/). The same principles apply when comparing electromagnetic radiation at different parts of the spectrum. Characteristic X-rays are emitted when outer-shell electrons fill a vacancy in the inner shell of an atom, releasing X-rays in a pattern that is "characteristic" to each element. Main purpose of this website is to help the public to learn some interesting and important information about materials and their properties. Due to the high energy and penetrating nature of x-rays, x-rays would not be reflected if they hit the mirror head on (much the same way that bullets slam into a wall). The Cookies Statement is part of our Privacy Policy. It may range from about 20 kV up to 300 kV. Fluoroscopy:Usesx-raysand a fluorescent screen to obtain real-time images of movement within the body or to view diagnostic processes, such as following the path of an injected or swallowed contrast agent. X-rays, also known as X-radiation, refer to electromagnetic radiation (no rest mass, no charge) of high energies. X-rays or Rntgen rays are the revolutionary discovery of the nineteenth century. Likewise, the distance from one peak to the next peak is also the wavelength. Characteristic X-rays can be used to identify the particular element from which they are emitted. iii) They are not deflected by electric and magnetic fields. X Rays have a wavelength ranging from 10-12 m (picometers) to 10-9 (nanometers). In 1901, Roentgen was awarded for his great work in this regard. En Espaol | Site Map | Staff Directory | Contact Us. ii) They undergo reflection, refraction, interference, diffraction and polarisation. So, x-rays are electromagnetic radiation just like the light around us but with much higher energy. Visit our Editorial note. The other corollary of this type of interaction is that the atom becomes an ion (it has lost an ejected electron! The remaining orbiting electrons will 'pack down' to fill the hole, and when changing orbits will lose energy and emit this as radiation. The radiation frequency is key parameter of all photons, because it determines the energy of a photon. Far infrared rays are thermal. The spectrum of electromagnetic waves changes gradually from lowest energy (radio waves and microwaves) to the highest energies (x-rays and gamma rays). The impacting electron will move off with reduced energy, and the ejected electron will move off in a different direction and speed with the remaining energy, there is an empty position in one of the shells. Where this energy can be written in the form of Joules. They have neither a positive nor a negative charge. X-ray Mirror. Characteristic X-rays are produced when a beam of accelerated electrons bombard the sample surface. Characteristic X-rays are produced when an element is bombarded with high-energy particles, which can be photons, electrons or ions (such as protons). The copper catches the electrons and the tungsten attenuates the photons produced in the copper. (New Torlc Sun.) The waves repeat and the distance for the wavelength to repeat. They have neither a positive nor a negative charge. Stabin, Michael G., Radiation Protection and Dosimetry: An Introduction to Health Physics, Springer, 10/2010. The electrons that hit the tungsten target undergo sudden deflection because of the interactions with the tungsten nucleus. Assume R(s)=0R(s)=0R(s)=0 at the index position. X-rays travel at the speed of light in a vacuum. Find the inverse Laplace transform of the function. The description above is a very high level description of wave properties. X-rays are produced when a metallic anode is bombarded/broken by very high energy electrons. X-rays can cause chemical and biologic damage to living tissue. The radiation frequency is the key parameter of all photons because it determines the energy of a photon. X-rays are a form of electromagnetic radiation. (3) It is electromagnetic transverse wave. X-rays are highly penetrating electromagnetic radiation and have proved to be a very powerful tool to study the crystal structure, in material research, in the radiography of metals and in the field of medical sciences. (By ANTHONY HOPE.) Physics of Nuclear Kinetics. Shared goals. ISBN-13: 978-1441923912. The tungsten target is usually angled to direct the resultant xrays towards a consistent portion or window in the tube wall.Some additions to this basic set up include the anode hood made of copper and tungsten that act like blinkers to prevent stray electrons from striking the walls of the tube. W. M. Stacey, Nuclear Reactor Physics, John Wiley & Sons, 2001, ISBN: 0- 471-39127-1. What if we compare the two waves and ask which has the higher energy? X-rays can cause some substances to fluoresce. Physics of Nuclear Kinetics. This visible light is just a small portion of all the electromagnetic radiation. Robert Reed Burn, Introduction to Nuclear Reactor Operation, 1988. X-Rays. There is a good deal of heat generated and hence the need for high melting points and the copper anode is able to conduct heat away effectively. Many materials are transparent to x-rays, while lead and other dense materials will not transmit the radiation. The change in energy is radiated as electromagnetic radiation. If two x-ray spectra have different shapes they are said to have different x-ray quality.
