Dose Driven Continous Scanning proton therapy offers reduced beam delivery time compared to discrete spot scanning but requires accurate characterization of temporal beam parameters for precise dose calculation. This study quantified rise time (trise) and pla...

To develop and validate a novel hybrid framework for five-material decomposition (water, fat, bone, iodine, and lung) using three-energy Photon-Counting CT (PCCT). By integrating multi-energy spectral analysis with density-constrained dynamic basis selection,...
