METHOD FOR ANALYZING MICROSTRUCTURE OF POROUS BODY, AND PROGRAM AND MICROSTRUCTURE ANALYZER FOR THE SAME

A method for analyzing a microstructure of a porous body is, for example, a method using porous-body data in which positional information providing a position of a voxel of a porous body obtained by three-dimensional scanning is associated with voxel type information including information that allows determination as to whether the voxel is a spatial voxel representing a space or an object voxel representing an object. This method includes (a) a step (S200, S300) of defining an imaginary surface that is in contact with at least one object voxel present on a surface of the porous body, and identifying, as opening-related voxels, spatial voxels that are in contact with the imaginary surface and a predetermined number or more of spatial voxels that continuously lie in a predetermined linear direction from the imaginary surface toward an inside of the porous body; and (b) a step of (S400, S500) of analyzing a microstructure of the porous body on a basis of the opening-related voxels.
