PO-0817: Clinical evaluation of intrafraction motion in mask system for Gamma Knife measured with IR tracking and cone-beam CT
Year: 2015
Type: conference-abstract
Abstract: S4103rd ESTRO Forum 2015 in a standard deviation, i.e. dosimetric precision, of 0.14 Gy between the gel and film measurement while differences of 0.11 Gy for the gel and 0.13 Gy for the film was found when comparing to the calculated dose distribution.Conclusions: Both gel and film reproduced the delivered dose distribution with only small deviations.In addition, the gel measurement showed slightly higher dosimetric precision than the film when compared to the calculated distribution.This study therefore shows that this 3D dosimetry system can provide dosimetric precision that is comparable with radiochromic film dosimetry.
