Monte-Carlo simulations of SPECT images are notoriously slow to converge due to the large
ratio between the number of photons emitted and detected in the collimator. This work …

The dual-energy contrast-enhanced digital mammography (CEDM) system based on a
photon counting detector (PCD) is very useful providing functional information for breast …

Gadolinium-159 (159Gd) is a beta emitter with appropriate energy for therapeutic
application. However, this radioisotope additionally emits gamma rays, enabling the …

To avoid imaging artifacts and interpretation mistakes, an improvement of the uniformity in
