X-Ray Tube

An X-ray tube is a device used in medical imaging to produce X-rays. It consists of a cathode and an anode enclosed in a vacuum-sealed glass or metal housing. When a high voltage is applied across the cathode and anode, electrons are emitted from the cathode and accelerated towards the anode.

The cathode is typically made of a heated filament, which emits electrons through a process called thermionic emission. The anode, on the other hand, is made of a metal target that is bombarded by the high-speed electrons. This interaction between the electrons and the anode target produces X-rays.

The X-rays generated by the X-ray tube can pass through the patient's body and are captured by a detector on the other side. The detector then converts the X-rays into an image that can be viewed by a radiologist or physician.

X-ray tubes are designed to handle high voltages and currents to produce the necessary X-ray energy. They also have cooling systems to dissipate the heat generated during the X-ray production process.

Overall, X-ray tubes are essential components in medical imaging systems, allowing healthcare professionals to diagnose and monitor various medical conditions.
