Introduction To X-ray Machines

It is a device that generates X-rays, mainly composed of an X-ray tube, an X-ray machine power supply, and a control circuit. The X-ray tube is composed of a cathode filament (Method), an anode target (Anode), and a vacuum glass tube. The X-ray machine power supply can be divided into two parts: a high-voltage power supply and a filament power supply. The filament power supply is used to heat the filament, and the high-voltage output end of the high-voltage power supply is clamped at both ends of the cathode filament and anode target, respectively, Providing a high-voltage electric field accelerates the active electrons on the filament to flow towards the anode target, forming a high-speed electron flow. After bombarding the anode target surface, 99% is converted into heat, and 1% generates X-rays due to bremsstrahlung. The entry introduces the development history, working principle, and structure of X-ray machines, and provides a detailed introduction to large and portable X-ray machines. Finally, it provides a detailed introduction to their applications.
