Robustness of 4D-optimized intensity-modulated proton radiation therapy and proton arc radiation therapy for stereotactic arrhythmia radio-ablation against cardiorespiratory motion

Background Stereotactic arrhythmia radioablation (STAR) is an emerging noninvasive treatment for refractory ventricular tachycardia. Proton therapy offers dosimetric advantages, but pencil-beam scanning is motion-sensitive. This study used an extended cardiac-torso (XCAT)-based 4...
