High-resolution CT is important for radiotherapy contouring and dose calculation. However, acquiring high through-plane resolution is often constrained by radiation dose, motion artifacts, and scanner limitations. This study aims to generate high-resolution (...
Radiomics-enabled adaptive radiotherapy depends on on-treatment imaging that maintains CT-like quantitative biomarkers. We evaluated whether HyperSight CBCT preserves planning-CT radiomic biomarkers more faithfully than conventional CBCT in pelvic radiotherap...
To test whether HyperSight CBCT (HS-CBCT) improves consistency of longitudinal radiomics with planning CT versus conventional CBCT in pelvic radiotherapy.

Iodine maps derived from Dual-Energy CT (DECT) provide critical biological information for radiotherapy treatment planning; however, conventional clinical iodine maps often mistakenly include bones due to insufficient X-ray spectral separation. In this study,...
Advancements in spectral CT imaging, particularly photon-counting CT (PCCT), have markedly enhanced diagnostic capabilities by exploiting the spectral properties of X-ray interactions. This technology delivers improved soft tissue contrast, superior material...
