Abstract
The present study intends to analyze internal radiation field of a typical mouse with voxel-based model and radiation transport code. 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 computer tools, which have been applied to process human-head images for 3-dimensional dosimetry in BNCT treatment at the Japan Atomic Energy Agency. Input files for particle and heavy ion transport code system (PHITS) were prepared from the constructed 3-dimensional voxel-based image data. Absorbed dose distributions and LET spectra in the mouse body were calculated by PHITS on the segmented images.
