(a) An adjustable single-slit collimator which enables modulation of the variable peak width. (b) For co-planar microbeam irradiation, mice were treated with a single set of irradiation in the prone position. (c) For cross-planar microbeam irradiation, mice were irradiated in stages by means of 90° rotation about the axis parallel to the microbeams. (d–f) The spatial dose distribution was confirmed using GafChromic film for `co-planar 100' (d), `cross-planar 100' (e) and `cross-planar 20' (f). Scale bar: 1 mm. |
