Internal radiation field of a typical mouse was analyzed by PHITS using a voxel-based model. A mouse was imaged by using the dedicated small-animal CT scanner, in which slice pitch was set at 0.1 mm. Each image with the resolution of 0.02 mm was segmented to construct a voxel-based model by using a computer tool JCDS, which have been applied to process human-head images for 3-dimensional dosimetry in BNCT treatment at the Japan Atomic Energy Agency. Input file for PHITS was prepared from the constructed 3-dimensional voxel-based image data. Distribution of deposition energy inside a mouse was calculated on the segmented images.
