Impact of Combining Advanced Dynamic Collimator Arc Therapy with Flattening Filter-Free Beams on Plan Quality and Delivery Efficiency In Postmastectomy Radiotherapy

RapidArc Dynamic (RAD) in Eclipse, version 18.1 integrates dynamic collimator rotation with static angle modulated ports (STAMPs) into arc to improve plan quality and treatment time. Flattening filter–free (FFF) beams further reduce beam-on time through highe...

Performance Comparison of a Plastic Scintillation Detector and Various Detectors for Small Field Dosimetry In High-Aspect-Ratio Rectangular Fields

Jaw geometry in elongated fields substantially impacts output factors (OPFs); therefore, reliance on square-field data alone cannot account for the physical effects. This study evaluated the response characteristics of various small-volume detectors in high-a...
