Enhanced dynamic wedge factors at off‐axis points in asymmetric fields
Several recent reports have described methods for calculating enhanced dynamic wedge factors (EDWFs). Many of these reports use the monitor-unit (MU) fraction method to predict EDWFs as a function of field size. Although simple in approach, MU fraction methods do not produce accurate EDWFs in large or asymmetric fields. A recently described technique, based on the MU fraction method works well ...
متن کاملCalculation of effective Enhanced Dynamic Wedge Factors from Segmented Treatment Tables for symmetric and asymmetric photon beams
Purpose: A method for determination of effective transmission factors of the Varian Enhanced Dynamic Wedge (EDW) is investigated. Methods and Material: The model assumes that the EDW factor equals the fraction of monitor units delivered to the geometrical center of the beam. This ”MU fraction approximation” is verified by comparing its predictions with measurements of a series of symmetric and ...
متن کاملDosimetric evaluation of a treatment planning system using pencil beam convolution algorithm for enhanced dynamic wedges with symmetric and asymmetric fields
Background: The dosimetric performance of Eclipse 6.5 three dimensional treatment planning system (3DTPS) is evaluated by comparing the calculated and measured dose in two dimensions following the guide lines of American Association for Physicists in Medicine Task Group 53. Materials and Methods: The calculations were performed by the 3DTPS for symmetric as well as asymmetric fields for standar...

15 صفحه اولOptimum reckoning of contra lateral breast dose using physical wedge and enhanced dynamic wedge in radiotherapy treatment planning system
Background: It was intended to investigate the effect of physical wedge (PW) and enhanced dynamic wedges (EDW) on contralateral breast dose during primary breast irradiation in radiotherapy treatment, using high energy photon beams. Materials and Methods: The Varian’s Clinac dual mode linear accelerator model 2100 C/D and Siemen’s Primus accelerators were used for radiation doses wi...
