Clinical Implementation of Non - Physical Wedges 1999 AAPM Refresher Course

چکیده
A non-physical wedge generates a spatial dose distribution similar to that produced by a physical wedge without a physical filter in the photon beam. Instead, an exponential fluence profile is produced via motion of one of the collimating jaws. Proposed in the late 1970s, nonphysical wedges have been implemented on both Varian and Siemens’ accelerators as the Varian Dynamic Wedge (DW) and Siemens Virtual Wedge (VW). Recently, Varian has introduced the Enhanced Dynamic Wedge (EDW) to add functionality to this modality.

متن کاملMonte Carlo study on beam hardening effect of physical wedges
Background: Physical wedges are still widely used as beam modifiers in external beam radiotherapy. However the presence of them in the beam trace may cause beam hardening which may not be considered in many treatment planning systems. The aim of this study is to investigate the beam hardening effect generated by physical wedges via different beam quality indexes as photon spectrum, half value l...

متن کاملA Monte Carlo simulation and dosimetric verification of physical wedges used in radiation therapy
Background: The presence of a wedge filter in the beam trajectory can modify the beam quality and cause some changes in the dosimetry parameters which are usually difficult to be measured directly and accurately. Material and Methods: In this study the MCNP-4C Monte Carlo code was used to simulate the 9 MV photon beam generated by a linear accelerator. Upon getting a good agreement bet...
