A mini-ridge filter is often used to widen the Bragg peak in longitudinal direction at low energies but not high energies. To facilitate clinical use of a filter, we performed planning study for feasibility as an integral part synchrotron nozzle (IMRF). Dose models with and without IMRF were commissioned commercial Treatment system (TPS). Dosimetric characteristics homogenous water phantom compared between plans fixed spread-out width 4 cm distal ranges varying from 8 30 g/cm². Six cases...

Abstract In magnetic resonance- (MR-) based adaptive workflows for an MR-linac, the treatment plan is optimized and recalculated online using daily MR images. The Unity MR-linac supplied with a patient positioning device (ppd) pelvic abdomen thermoplastic masks attached to board high-density components. This study highlights dosimetric effect of this in such when there are relative patient-ppd displacements, as these not visualized on imaging planning system assumes fixed ppd. adapted plans...

Abstract The halo portion of a proton therapy dose creates long tail in distributions, but so far study this phenomenon has been limited. We used statistical methods and mathematical models to confirm that the long-tailed distributions exhibits power-law relationship. By analyzing 299 measured profiles, we found all lateral had significant scaling correlation with high coefficient tail. set up dual-mechanism model, containing both direct indirect impact mechanisms. In mechanism, proximal...
