Abstract

This report describes measurements of the radiation dose from the MRI-linac at Liverpool Hospital (Australia) using a selection of detectors (such as ionisation chambers, alanine and Gafchromic EBT-3 films) in order to calibrate the machine output. Absorbed dose to water calibration coefficients for the ionisation chambers used in the constant magnetic field (1 T) of the MRI-Linac machine were also measured. Together with similar measurements performed at NPL in a 0 T magnetic field over a range of beam qualities, the corrections required to measure the absorbed dose in the presence of a magnetic field using these detectors was determined.
