METHOD FOR MEASURING VOLUME RATIO OF EACH CONSTITUENT MEDIUM EXISTING IN MINIMUM UNIT OF X-RAY CT IMAGE FOR SPECIMEN FORMED OF COMPLEX MEDIUMS

摘要

In performing an X-ray CT scan on a specimen, the volume which each constituent medium accounts for, that is, the volume ratio of the constituent medium mixed in a mixel can be calculated for the corresponding mixel, in which the constituent medium is mixed, among a voxel of the specimen, thereby measuring the volume ratio of each constituent medium existing in the minimum unit in the X-ray CT scan.
