X-RAY EQUIPMENT COMPONENTS & APPLICATIONS

Radiography is an imaging technique that uses electromagnetic radiation other than visible light X-rays are used  to view the internal structure of a non-uniformly composed and opaque object (i.e. a non-transparent object of varying density such as the human body. X-rays are produced in the x-ray tube which is located in the x-ray tube head. X-rays are generated when electrons from the filament cross the tube and interact with the target. The heart of an X-ray machine is an electrode pair -- a cathode and an anode -- that sits inside a glass vacuum tube are explained..X-ray beam collimation for radiography and fluoroscopy projection imaging is important for patient dose and image quality reasons. Collimators are explained with pictures.Imaging  Grids: The X-ray grid will effectively remove the scatter produced between the beam and the film producing a more effective subject contrast. It is shown in figures and its use is explained. Thermionic Emission &  Rotating anode tube are  explained.X-ray tube is always mounted inside a lead-lined protective housing that is designed to-Prevent excessive radiation exposure. Cooling of X-ray Tube Thermal Over load detector  High-frequency generator produces a high-frequency high-voltage AC waveform. Photo fluorography cassettes are mentioned. Computed radiography (CR) cassettes use photo-stimulated luminescence screens to capture the X-ray image .  Complete picture of X-ray tube pictures are given with flat panel detectors.
