1. A region recognition result correction apparatus, comprising: a recognition means for receiving input of a plurality of tomographic images, each of which represents a cross section perpendicular to an axis of a human body at a plurality of different positions along the axis of the human body, recognizing a single anatomical portion from among a plurality of different regions which are arranged along a direction of the axis of the human body within each of the tomographic images, and for recognizing the anatomical portions represented in each of the tomographic images such that the order in which the anatomical portions recognized within the plurality of tomographic images are arranged matches the order of anatomical portions of the plurality of different anatomical portions along the direction of the axis of the human body, which is prepared in advance, when the anatomical portions recognized within the plurality of tomographic images are arranged in the order that the corresponding tomographic images are arranged; a recognition result display control means, for displaying each of the plurality of tomographic images on a screen with the anatomical portion recognized therein by the recognition means; input receiving means, for receiving input that specifies a correction position, which is a position between two adjacent tomographic images, with respect to the display on the screen by the recognition result display control means; and an anatomical portion correcting means, for detecting boundary positions, at which the anatomical portions recognized by the recognition means differ between two adjacent tomographic images, in both the upper and lower directions along the axis of the human body from the correction position, determining a plurality of tomographic images, which are positioned between a boundary position which is closer to the correction position from among the boundary positions detected in the upper and lower directions and the correction position as erroneously recognized tomographic images, and for correcting the anatomical portions recognized by the recognition means within the erroneously recognized tomographic images to the anatomical portion recognized by the recognition means within the tomographic image which is not determined to be erroneously recognized tomographic images, from between the two tomographic images which are positioned to sandwich the closer boundary position therebetween.
