Imaging process of computer X-ray photography

1->； 2.x-rays pass through the human body and are absorbed by IP to form a latent image.

2->； 3. By laser excitation, IP releases photons, which are converted into electrical signals by photomultiplier tubes.

3->； 4. The image is stored in the computer or printed into film through digital-to-analog conversion.

4->； 1: Because the energy stored in the photo-excited phosphor will not be completely released during laser reading (there are still afterimages), it is necessary to brush off the imaging board with high-intensity fluorescent lamp for the next imaging.
