Radiation detection
•
Inorganic crystal that emits visible light photons after
interaction of photons with detector.
Desired for PET:
1. High stopping efficiency
2. Good energy resolution
Scintillation detectors
•
# of scintillation photons is proportional to the energy
deposited in the crystal.
•
Important properties for application in PET:
•
Stopping power for 511 keV photons
•
Signal decay time
•
Light output
•
Intrinsic energy resolution
