Domain-specific¶
- Photon-Counting Computed Tomography
- Pulse pileup merges events that arrive too close in time; dead time loses counts; charge sharing can split one interaction across pixels; fluorescence escape and Compton scatter can move deposited energy; detector gain and threshold dispersion create channel-to-channel bias
This sourceReview enumerating photon-counting-detector nonidealities, including gain and threshold dispersion producing channel-to-channel bias. Review describing how pulse pileup at high flux makes recorded counts nonlinear and shifts the apparent recorded spectrum toward higher energies.
