Task Group No. 218 - Tolerance Levels and Methodologies for IMRT Verification QA AAPM Members, Affiliates and Non-Member Affiliates - Login for access to additional information Charge To review literature and reports containing data on the achieved agreement between measurements and calculations for fixed-gantry IMRT, Tomotherapy, and VMAT techniques. To review measurement methods commonly employed, composite of all beams-actual parameters, composite perpendicular, and beam-by-beam perpendicular. Discuss pros and cons of each. To review single-point (small-averaged volume), 1D and 2D analysis methodologies for absolute dose verification with ion-chamber and the more complex 2D detector arrays, mainly performed with dose differences comparison, distance-to-agreement (DTA) comparison between measured and calculated dose distributions, and a combination of these two metrics (gamma method). To investigate the dose-difference/DTA and gamma verification metrics, their use and vendor-implementation variability, including the choice of various parameters (normalization method, choice of dose thresholding, points shift) used to perform the analysis.
