Abstract:
INTRODUCTION:Using physical wedges (PWs) to modify dose distribution and more homogeneous target coverage is a well-established technique. However, there are many problems with PWs known as beam hardening, which made them problematic. This can be overcome by dynamic wedges which do not filter beam. Comparison of physical properties of physical and enhanced dynamic wedges (EDWs) restricted to homogeneous medium. Hence, the main aim of this study is to compare dosimetric properties of physical and EDWs at bladder inhomogeneous phantom as a most common case implementing wedges. MATERIALS AND METHODS:An inhomogeneous pelvic phantom with homogeneities of uterus, femur, soft tissue, rectum, and bladder was designed. Eclipse treatment planning system with the aim of bladder target was used for calculations. All dose distributions were measured with EBT3 films. RESULTS:Comparison between beam profiles of physical and EDWs at wedged and nonwedged directions shows a greater difference at near inhomogeneous soft tissue interface and also at heel side of wedges. CONCLUSION:Little difference observed between dose distribution of physical and EDWs shows neglectable effect of beam hardening produced by PW compared to EDW at inhomogeneous medium. Furthermore, EBT3 films present good feature to measure dose distributions at EDW fields.
