Gafchromic films mounted behind mouse ears show the irradiation pattern for non-irradiated ears (1) and irradiations with σ/ctc-ratios of 0.053 (2), 0.11 (3), 0.17 (4), 0.23 (5), 0.31 (6) and 0.49 (7) at ctc = 1.8 mm each. (7) corresponds to a homogeneous dose distribution. Owing to the limited sensitivity range of the films, no absolute dose values or minibeam sizes can be extracted from these images.
