radiotherapy of prostate cancer using rapid arc

RapidArc is a novel technique using arc radiotherapy aiming to achieve intensity-modulated radiotherapy (IMRT)-quality radiotherapy plans with shorter treatment time. This study compared the dosimetric quality and treatment efficiency of single-arc (SA) vs. double-arc (DA) and IMRT in the treatment of prostate cancer.

RapidArc is an “IMRT Arc therapy” using a single rotation of the linac gantry to deliver a precise IMRT plan following IGRT and OBI targeting. This “volumetric arc,” often labeled VMAT, for Volumetric Arc Therapy, enhances both the delivery and the targeting of prostate cancer radiation.
