Dosimetric Influence of Acuros XB Dose-to-Medium and Dose-to-Water Reporting Modes on Carcinoma Cervix Using Intensity-Modulated Radiation Therapy and Volumetric RapidArc Technique.

The present study reveals the important difference between AAA, AXB-D, and AXB-D computations for cervix carcinoma using IMRT and RA techniques. The inter-patient variability and systematic difference in dose-volume parameters computed using AAA, AXB-D, and AXB-D algorithms present the possible impact on the dose prescription to PTV and their relative constraints to OARs for IMRT and RA techniques. This may help in the decision-making in clinic while switching from AAA to AXB (D or D) algorithm for cervix carcinoma using IMRT and RA techniques.
