Photon-counting computed tomography (PCCT) is recognized as a revolutionary technology for next-generation spectral imaging. However, spectral distortion and count loss induced by pulse pile-up effects (PPEs) at high X-ray fluxes severely hinders its quantita...

Ion beam radiotherapy (helium and carbon) has opened new frontiers for FLASH research by introducing LET as a critical physical parameter for mechanistic investigation. However, current FLASH effect models are restricted to low-LET irradiation, and high-LET a...

The dual-layer flat-panel detector (FPD) has great potential in dual-energy cone-beam CT imaging. However, like the scatters from the detector housing in conventional single-layer FPD, the scatters from the top layer and some aluminum or carbon panels between...
