<P>PROBLEM TO BE SOLVED: To provide a diagnosis supporting apparatus, a diagnosis supporting method, a lesion detection apparatus and a lesion detection method for supporting diagnosis by detecting regions with suspected lesions "where a papillary swelling is generated on the surface (the outermost surface) of an inner wall" and "where cells (epithelial cells) randomly proliferate on the surface (the outermost surface) on the inner wall" if such regions exist on the inner wall within a living body with a flat surface such as the bilary tract and the pancreatic duct. <P>SOLUTION: An arithmetic operation processing device 90 of an OCT apparatus 1 detects the position of the surface of the inner wall of the bilary tract or pancreatic duct from three-dimensional structure data, and calculates an evaluation value of the surface roughness from the shape of the surface. A region with a high evaluation value and a high surface roughness is detected as a lesion "where the papillary swelling is generated on the surface (the outermost surface) of the inner wall", etc. The evaluation value of the surface roughness is obtained by setting a plurality of points for measurement on the surface of the inner wall and adding absolute values of the amount of inclination on the surface of the inner wall at the respective points for measurement by prescribed region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
