Accurate patient setup in deep inspiration breath hold (DIBH) proton therapy is critical due to steep dose gradients, limited range robustness, and the frequent use of tight clinical target volume (CTV) margins. This study introduces a CT-on-Rails (CTOR)–base...

Lung tumors are poorly visible on conventional on-board 2D X-ray imaging due to limited soft-tissue contrast and overlapping anatomy, posing a challenge for patient setup on proton therapy systems equipped with 2D X-ray imaging. Our goal is to develop a novel...
