Comparison of dose distribution in axial and coronal planes using (a) the IMRT and (b) VMAT techniques along with their (c) DVH. IMRT, intensity-modulated radiation therapy; VMAT, volumetric modulated arc therapy; DVH, dose-volume histograms; PTV, planning target volume.|@|~(^,^)~|@|Gamma analysis of a representative patient. (a) ArcCHECK-measured plan, (b) TPS-calculated plan, (c) difference between the ArcCHECK-measured and TPS-calculated plans, and (d) measured points that matched the acceptance criteria were shown in yellow color and points that don't match acceptance criteria were shown in red color. TPS, treatment planning system.|@|~(^,^)~|@|The rate of dose falloff beyond the target by plotting ln (D) versus ln (1/V) for (a) supraglottic larynx, (b) hard palate, and (c) tongue cancers. IMRT, intensity-modulated radiation therapy; VMAT, volumetric modulated arc therapy.
