To validate a planning-quality HyperSight iCBCT protocol on a C-arm LINAC for head and neck (HN) offline adaptive planning. By enabling direct use of high-quality CBCTs for re-planning, this approach aims to streamline the offline adaptive workflow.

To develop a cost-effective, open-source system for patient-specific voluntary breath-hold (VBH) during CT simulation. The goal is to provide accurate gating thresholds for LINAC systems, such as Varian Truebeam Real-time Position Management (RPM) and auto-be...

Kilovoltage cone-beam CT (kV-CBCT) is routinely used for image-guided radiotherapy (IGRT). However, image artifacts and limited Hounsfield unit (HU) stability strict its application in adaptive radiotherapy. Recently, HyperSight CBCT was introduced to C-arm l...
