To evaluate the feasibility and accuracy of surface-guided radiotherapy (SGRT) for setup and intrafraction motion monitoring in routine brain IMRT using open-face masks, and to assess whether immobilization device type affects monitoring performance.
Motion management plays a critical role in radiation therapy for thoracic and abdominal tumors, where respiratory motion can significantly compromise treatment precision. Among available motion-mitigation techniques, respiratory gating offers distinct advanta...
The increasing adoption of MRI-guided online adaptive radiotherapy (oART) has improved treatment personalization but introduced substantial technical complexity and time pressure. Existing QA approaches remain largely manual and retrospective, with limited ab...
Positron Emission Tomography/Computed Tomography (PET/CT) plays a pivotal role in radiation therapy, particularly in tumor delineation, response assessment, and adaptive therapy planning. However, the reliability of PET/CT depends on key system performance an...
CBCT-based online adaptive radiotherapy (CBCT-oART) enables daily plan adaptation but is sensitive to intra-fraction motion during extended adaptive workflows. This study evaluates breath-hold (BH) motion stability and workflow impact using an in-bore surface...
Magnetic resonance imaging-guided online adaptive radiotherapy (MRgRT) requires a complex planning process, during which an upstream peer review prior to physician approval plays an essential role in early error detection and supporting safe and efficient onl...
