Investigation of High Dose Rate (HDR) Brachytherapy: Prostate Treatment Planning and Dose Delivery Accuracy Charles M. Able, MS Department of Radiation Oncology, Wake Forest University School of Medicine, Medical Center Boulevard, Winston-Salem, North Carolina 27157, USA Ashley N. Graham Department of Biological and Physical Sciences, South Carolina State University, Orangeburg, SC 29117, USA Abstract Objective: The focus of this study is to determine the accuracy of treatment planning and delivery (Varian TM BrachyVision-VariSource) by performing in-vivo dose measurements using MOSFET dosimeters (MDs). Materials and Methods: Thomson-Nielsen MOSFET Dosimetry System (MOSFET model 502RD) was used as the dosimeter to measure dose distributions. MDs were calibrated against a Farmer-type ionization chamber at distances of 1.6 cm and 4.9 cm from 192 Ir in water. A surrogate patient consisting of anatomically correct prostate, bladder, rectum, and urethra was developed utilizing Vyse Ordance TM
