(2026) Bassermann | PCCT reduces beam-hardening effects in proton stopping-power estimation
This phantom study compared photon-counting CT (PCCT), dual-energy CT (DECT), and single-energy CT (SECT) for proton stopping-power ratio (SPR) estimation, specifically testing how phantom size and insert position affect accuracy through beam hardening. Two SPR methods were evaluated: a DECT-based Saito method and a…
(2026) Lustermans | PCCT enables robust low-dose proton therapy planning across patient sizes
Photon-counting CT (PCCT) maintained consistent proton range estimation (R80) across different phantom sizes, tissue types, proton beam energies, and imaging doses, whereas dual-energy CT (DECT) became increasingly inaccurate in larger phantoms at reduced radiation dose. Even at low-dose imaging (CTDIvol 5 mGy), PCCT kept…
