Abstract

This report describes measurements of the radiation dose from the MR-linac at The Royal Marsden Hospital, Sutton using a selection of detectors (such as ionisation chambers and alanine) in order to calibrate the machine output. Absorbed dose to water calibration coefficients for the ionisation chambers used in the MR-linac machine when the constant magnetic field was either on (1.5 T) or off (0 T) were also determined. 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 can be determined.
