The ERC funded iMPACT project at INFN and Padova University aims at developing a high resolution and extremely fast pCT scanner. A clinically viable pCT requires a proton rate $>100$ kHz/cm${}^2$, which can be sustained combining a silicon MAPS-based tracker and a highly segmented range calorimeter of PVT scintillators. The focus of this contribution is the design of the calorimeter, which has been simulated using the Geant4 Gate application, to characterize the scintillation and photon detection in a single PVT element and provide a parametric response for the complete system. Such studies are compared to measurements collected at the TIFPA proton beamline.
