The production of X-ray images is a complex process that uses electromagnetic radiation. X-rays are high-frequency energy waves that penetrate through the body or the target organ and are either absorbed, reflected off, or traversed through the body. The X-ray tube, which produces the X-ray, is composed of a cathode and an anode. The cathode is a tungsten filament, which is heated during the ...
