چکیده
Proton pencil beam scanning is a dynamic delivery technique with excellent conformability to the tumor volume. The accuracy of spot size and positions will have significant effect on delivered dose distribution. We employed polymer gel dosimeters measure for Shanghai Advanced Therapy facility (SAPT). Polymer (MAGAT-f PAGAT) were utilized full width at half maximum (FWHM) various depths basis their MRI readouts. correlation between FWHM standard deviation (σ) was analyzed different depths. measured Bragg peak range compared Monte Carlo (MC) simulation. Three-dimensional volume rendering reconstructed 3D visualization three-dimensionally. R2 dose–response curve investigated dosimeters. deviations ranging measurement simulation 0.13% −0.53% MAGAT-f PAGAT, respectively. Our results ascertain feasibility dosimeter proton beam.

PURPOSE To obtain and assess the accuracy of 3D dose distributions and LET maps from a passively-scattered proton beam through the use of LET-dependent and LET-independent polymer gel formulations. METHODS Dose measurements were performed with BANG3-Pro2 (MGS Research, Inc, Madison, CT) polymer gel dosimeters. The dosimeters were mixed from kits and were poured into 14.5 cm high by 15 cm diam...
