- Each value was calculated from the data for all 10 patients. Values are expressed as mean ± SD. sIMRT step-and-shoot intensity-modulated radiotherapy, dIMRT dynamic intensity-modulated radiation therapy, VMAT volumetric-modulated arc therapy, Tomo helical tomotherapy. a: sIMRT vs dIMRT, b: sIMRT vs VMAT, c: sIMRT vs Tomo, d: dIMRT vs VMAT, e: dIMRT vs Tomo, f: VMAT vs Tomo. If c is in the “p value” column, it means that there is statistical significance between sIMRT and Tomo
