
Basic configuration of CR (=Computed Radiography) system
• Developed and used a , called
“Imaging Plate”
- The function of
“
I
maging Plate”
1) Imaging plate is a flexible plate of 1mm or less thickness coated with fine photostimulable phosphorus
crystal.
2) Temporarily stores the X-ray energy image in portion to the X-ray intensity it receives.
3) The stored energy is released as visible light when a laser in the CR Reader scans the IP.
This phenomenon is generally called “photostimulable luminescence” (PSL)
4) The image on the imaging plate is erased when exposing excessive light.
• Emit the blue light by laser beam scanning.
• The image reader ( = FireCR flash ) converts the latent image on the imaging plate into digital signal.
