- •
The collimator dimension and energy window to detect proton-induced gamma rays were optimized.
- •
Images of prompt gamma ray were reconstructed by two methods (analytic- and iterative method) and compared with each other.
- •
Reconstructed data were compared with the amount of dose deposited by proton beam.
