NExt oral radiology: X ray tube
In dental radiography, X-ray tubes are essential for producing X-rays used in diagnostic imaging. The X-ray tube in dental treatment consists of several key components that work together to generate and control the X-ray beam. Here are the main components: 1. **Cathode:** - The cathode is the negative electrode of the X-ray tube. - It consists of a tungsten filament that emits electrons when heated through a process called thermionic emission. 2. **Anode:** - The anode is the positive electrode of the X-ray tube. - It typically consists of a rotating tungsten disk. - The anode serves as the target for the electrons generated by the cathode, producing X-rays when bombarded by high-speed electrons. 3. **Focusing Cup:** - The focusing cup is a part of the cathode that focuses the emitted electrons into a beam before they strike the anode target. - It helps to concentrate the electron stream, enhancing the sharpness of the X-ray beam. 4. **X-ray Tube Housing:** - T
