A Brief Description of the Radiology X-Rays and Its Uses in Medical Imaging
X-rays belong to the class of the electromagnetic rays with a frequency that is within the range of the 30 petahertz to 30 exahertz. The energy of the x-rays lie within the range of 120eV to 120 keV. They are also known as the Rontgen radiation that is named after the scientist who discovered these rays. Hard X-rays have the power to penetrate solid objects and find their most optimum use in medical science as well as the crystallography. X-rays are generated by the X-ray tube that is nothing but a vacuum tube using high voltage in order to accelerate the electrons that are released by a hot cathode to high velocities. The high speed electrons then hit the metal that is the anode to create the X-rays. Within one month after the release of the seminal paper by Rontgen, the X-rays were used in the process of medical imaging.
Radiology is that branch of medical science that deals with obtaining the medical images of various body parts that need to be observed. The capability of the radiology X-rays to penetrate hard material is one of the prime reasons that make it so useful to the medical scientists. Some of the most important uses of the radiology X-rays are in determining the chest X-rays that can be used to identify the lung diseases like lung cancer, pneumonia, pulmonary edema. Another prime example is that of the abdominal x-ray that can be used to detect the free air from the visceral perforations, free fluid (in ascites). Along with the plain X-rays and the CT scans, physicians also use fluoroscopy as an X-ray test methodology.
