Abstract:
1. An image processing method for processing a sectional image, wherein the sectional image is divided into a pixel group including artifacts and a pixel group without any artifacts by carrying out a feature quantity analysis of the artifacts, and a correction process is carried out to remove the artifacts by performing a predetermined process relating to correction only with respect to the pixel group including the artifacts, and wherein the feature quantity analysis is an independent component analysis, and using the independent component analysis, a separation is made independently into image components corresponding to the artifacts and image components not corresponding to the artifacts, thereby dividing into the pixel group including the artifacts and the pixel group without any artifacts, wherein the predetermined process relating to correction is performed only with respect to the pixel group including the artifacts by eliminating image components corresponding to the artifacts, wherein, with a sectional plane of the sectional image regarded as an x, y plane, and each pixel of the sectional image regarded as F (x, y), the sectional image F (x, y) is divided by the x, y into groups, Δ in number, thereby to obtain images F and wherein basis function(s) A
