5.3 Processing
1. Red laser light stimulates the sensitive surface of the
imaging plate.
2. Imaging plate glows blue light in relation to the amount
of X-ray information stored to the plate.
3. Glowing blue light is optically collected pixel by pixel
(line by line) and measured with extremely sensitive
photodetector.
4. Digital image is formed from the measured light intensi-
ty variation.
After stimulating, imaging plate is exposed to bright light,
which clears the remaining image information from the
plate. The imaging plate is dropped out of the unit.
X-ray exposures and processing are not aging the imaging
plate, so it is re-usable hundreds of times. In practice,
mechanical wearing limits the service life of the plate.
