Please TYPE the answer List components a planar X-ray radiography system made and write a short description for each component focusing on the what each does and how? Solution A planar x-ray radiography system is made up of the following components: 1) X-ray tube 2) Collimator 3) Anti-scatter grid 4) Digital detector 1) X-ray tube The X-ray tube is where the X-rays are produced. To produce the X-rays, the electrons are accelerated and then abruptly stopped, in this way the photons that constitute the ionizing are obtained. The tube consists of a metallic filament (cathode) that when put incandescent produces a cloud of electrons around it (termiionic effect). These electrons are accelerated by a high deference of potential (kV), where they collide with the anode and are stopped releasing kinetic energy as photons that constitute the x-rays. 2) Collimator A collimator is a system that allows me to homogenize the trajectories or rays that are emitted by a source. Because the radiation propagates in all directions, it is necessary to delimit the rays or restrict them in order to direct them to where the patient or the detector is located. 3) Anti-scatter grid The factor responsible for obtaining poor quality radiographs is often scattered radiation. By eliminating scattered radiation from the X-ray beam, the grid eliminates the source of reduced contrast. It is a device between the patient and the receiver of the image, its purpose is to absorb scattered radiation, which improves the quality of the image. In most of the equipment are plates of several mm thick that have in their interior a series of very thin sheets of Pb and W. 4) Detector The detectors generally consist of a hollow metal cylinder on whose axis there is a conductive wire, held at the ends by insulating covers. Said conductor is maintained at a positive potential while the tube serves as a cathode. The tube is filled with a suitable gas, and a side window allows the radiation to enter. The incident photons are absorbed in the gas by photoelectric effect and the emitted radiation is absorbed again to produce new electrons. With an applied voltage the acceleration of the electrons causes the signal to multiply, which is proportional to the original number of electron-ion pairs, which in turn is proportional to the energy deposited by the registered photon. .
