X-ray, a radiogram made by exposing photographic film to X-rays; used in medical diagnosis.X-ray, are special pictures of the inside of your body. A doctor will decide when you need an x-ray and what body part needs to be x-rayed. An x-ray machine, not a camera, is used to take these pictures, when the picture comes out it won't like the ones in your photo album, but doctors have learnt how to look at these pictures. Doctors can see broken bones, lung infections, and more.(1)(a) Relatively high-energy photon having a wavelength in the approximate range from 0.01 to 10 nanometers.(b) A stream of such photons, used for their penetrating power in radiography, radiology, radiotherapy, and scientific research. Often used in the plural. Also called reontgen ray.(2) A photograph taken with x-rays.Means electromagnetic radiation of short wave-length produced when high-speed electrons strike a solid target....

Gamma ray
A very penetrating electromagnetic ray not appreciably deflected by a magnetic or electric field emitted by radioactive substances Gamma rays are photons of electromagnetic radiation having a wavelength shorter than that of X rays i e shorter than 01 nanometer and are correspondingly more penetrating than X rays In addition to being given off in certain types of radioactive decay they may be found in cosmic radiation though they are largely absorbed by the earths atmosphere Gamma ray detectors orbited above the atmosphere have found bursts of gamma radiation in some cases associated with visually observed supernova explosions but in most cases from unidentified sources...
Roumlntgen ray
An X ray originally the term was applied to any of the rays produced when cathode rays strike upon surface of a solid as the wall of the vacuum tube but now it refers specifically to electromagnetic radiation having wavelengths from 10 3 nm to 10 nm immediately below ultraviolet radiation on the wavelength scale Roumlntgen rays are noted for their penetration of opaque substances as wood and flesh their action on photographic plates and their fluorescent effects They were called X rays by their discoverer W K Roumlntgen They are one of the forms of ionizing radiation which can have damaging effects on living cells They also ionize gases but cannot be reflected or polarized or deflected by a magnetic field They are used in examining opaque objects especially in medicine for visualizing organs and other objects inside the human body as for locating fractures or bullets and examining internal organs for abnormalities...
magnetic resonance imaging
a medical diagnostic procedure utilizing the phenomenon of nuclear magnetic resonance to generate images of internal parts of the body It depends on the differential absorption of electromagnetic radiation by different types of living tissue in a magnetic field It is complementary to X ray imaging in that the softer tissue show more prominently in magnetic resonance images rather than bone as with X rays It is a non invasive procedure allowing such images to be obtained without penetration of the tissue by objects It is abbreviated MRI As with computerized tomography the results are usually presented as images of sequential planar sections of that part of the body of concern to the physician...

Fluoroscopy
Examination of an object as the human body by exposing it to the X rays and observing the shadow cast upon a fluorescent screen cryptoscopy...
