access roentgenogram tubes are a critical aspect of all roentgenogram imaging systems and the central site of roentgenogram production. They are a persona of the imaging system that radiologic technologists do non interact with, as it is set(p) in protective housing and out of reach. Despite the tubes location, it is a radiographers responsibility to understand its construction and operation. While not all roentgenogram tubes are the same, there are critical part that all tubes must contain in order to create x-rays, such(prenominal) as the cathode an anode. Both the cathode and anode are considered electrodes, or conductors through which electricity enters or exits an object. X-ray tubes contain two electrodes and can be further categorise as diodes. Diodes are semiconductor devices with two terminals that allow for the merge of rate of flow in only one direction. In the x-ray tube this flow is directed from cathode to anode. The purpose of this paper is to describe the dif ferent parts that subscribe up an x-ray tube, both internally & externally, and briefly describe the piece that each part of the tube plays in the in the process of x-ray production.Literature ReviewX-ray tube structure can be divided into the external components, and internal components. The external components consist of the protective housing, an gasbag and insulating oil. The internal components include the negatively charged cathode, and positively charged anode. external componentsThe components necessary for the production of x-ray are housed in a glass in or metal envelope. The envelopes primary purpose is to tin a vacuum for the x-ray tube, allowing the improved flow of electrons from cathode to anode. The envelope too provides insulation from heat and electricity given off. Dielec... ...production, while the angle of the anode interacts with x-ray photons. An anodes angle affects both the effective focal spot size as well as the intensity of the x-ray beam that ex its the tube. X-ray tubes containing rotating anodes possess an assembly of induction-motor electromagnets known as the stator and rotor coil, mechanisms necessary to one shot the target. The stator is the only section of the cathode that is located outside of the tube envelope. It is make up of electromagnets that surround the neck of the x-ray tube. The rotor is a positively charged hollow copper cylinder attached to the anode by a molybdenum shaft. It is located within the stator and inside of the tube envelope. The rotor rotates at high speeds due to the current that runs through each stator, which induces a magnetic field that surrounds the rotor and interacts with the ferromagnetic copper.
