Effective radiotherapy for upper abdominal tumors requires dose escalation but is limited by respiratory motion and the low gastrointestinal radiation tolerance. Current clinical motion management on conventional Linacs relies on simple external surrogates th...

Mobile CT and CBCT systems improve flexibility and reduce patient transport burden in HDR gynecologic brachytherapy. However, competition for imaging resources remains a practical limitation. This work evaluates the Varian Ethos linear accelerator equipped wi...

Radiotherapy for upper abdominal cancers is limited by respiratory motion and the low radiation tolerance, restricting safe dose escalation. Conventional linear accelerators rely on kV X-ray and CBCT imaging but lack real-time internal motion tracking capabil...
