Question

During CR imaging plate processing, when the laser frees trapped electrons, allowing them to return to a lower energy state, which type of light photon is released?

Select one:
a. red-orange
b. ultraviolet
c. blue-purple
d. green-yellow

Answer 1

In CR imaging plate processing, the released light photon is typically blue-purple when the stored energy is released by the laser.

Step-by-step explanation:

During CR (Computed Radiography) imaging plate processing, when the laser frees trapped electrons, allowing them to return to a lower energy state, the type of light photon that is released is typically in the blue-purple spectrum. This process is characteristic of photostimulable phosphor plates (PSPs) used in CR technology. When the laser scans over the imaging plate, it prompts the release of energy stored by the phosphors during exposure to X-rays, in the form of light photons that can then be detected and converted into a digital image.
