- •
ET images are obtained using an image reconstruction involving a system matrix (SM).
- •
Analytical and Monte Carlo simulations can be used to calculate this SM.
- •
Accurate modeling of the detector response for SM calculation is essential.
- •
The accuracy of SM directly impacts the reliability of reconstructed images.
- •
Comprehensive modeling of all detector response components raises large challenges.
