Cone-beam CT (CBCT) is routinely used for image-guided radiation therapy (IGRT); however, in the optimal frequency of CBCT varies across patients and treatment sites, affecting imaging dose, workflow efficiency, and clinical consistency. This study aims to de...

Proton dose calculation is sensitive to the metal wires, which are placed on the patient's skin during CT simulation to precisely outline the location of surgical scars and the intended radiation treatment field borders. In order to avoid the dose uncertainti...
HyperSight cone-beam CT (HS-CBCT) on C-arm linacs may enable CBCT-based replanning by improving image quality, HU fidelity, and field-of-view (FOV). We evaluated clinical feasibility and dose-recalculation agreement using patient data.
To evaluate how varying the noise-suppression level and reducing the imaging exposure affects contrast-detail performance and other image quality metrics in image-guided radiation therapy.
Teaching medical physics to radiation oncology residents is challenging, given their limited foundational training in physics, competing clinical demands, and inconsistent motivation beyond preparation for the ABR physics examination. Meanwhile, clinical medi...
