Irradiation doses received at the two alternative minimum dose locations (positions D and F) and at the maximum dose location (position H) inside the IC of the IMTC, and the dose received at the reference dose location (position B). Also reported are the ratios of the doses received at each location (positions D, F and H) for the three ICs with reference to the doses received at the reference location (B) and the dose uniformity values (H/D and H/F). All runs were performed on 25 July 2019 using an irradiation time of 3.85 minutes to deliver an estimated dose of 150 Gy at position D.
