Task Group No. 351 - Clinical reference dosimetry in MR-guided radiotherapy (TG351)

AAPM Members, Affiliates and Non-Member Affiliates - Login for access to additional information

Activities
To develop guidelines for reference dosimetry in MR-Guided high energy photon RadioTherapy (MRGRT) units. The task group will:
  •  Review and evaluate existing literature on calculated and experimental data sets for magnetic field-dependent beam quality conversion factors.
  • Review and determine ‘reference setup conditions’ for measurement of beam quality and reference dose. This is necessary as in some of the units, the standard TG-51 defined reference setup conditions cannot be achieved.
  • Review, evaluate and identify appropriate reference-grade ionization chambers and measuring instruments for reference dosimetry in the presence of a magnetic field.
  • Review and evaluate the sources of uncertainty and determine an uncertainty budget for MRGRT reference dosimetry.
  • Produce an AAPM Task Group report on reference dosimetry for MR-guided high energy photon radiotherapy based on findings in charges a-d in line with the current internationally accepted reference dosimetry protocols.
  • Collaborate with the Ionization Chamber Registry Working Group (WGICR) to incorporate relevant parameters/data for MRGRT appropriate reference-grade detectors into the registry.
