1. A region recognition result correction apparatus comprising: a recognition result display control means that causes the following to be displayed on a screen: a plurality of tomographic images representing a plurality of regions of a subject or a reconstructed image based on the plurality of tomographic images; and results of recognition processing of the regions of the subject represented by the respective tomographic images, wherein the positional relationship of the regions recognized in the respective tomographic images between the tomographic images matches with the anatomical positional relationship of the plurality of regions of the subject; a correction information input accepting means that accepts input of correction information capable of identifying a correction position which is supposed to be a boundary of different regions and used for correcting a result of the recognition processing; and a region correction means that determines an incorrectly recognized tomographic image whose result of the recognition processing is incorrect and a correct recognition result representing a correct region of the incorrectly recognized tomographic image based on at least either one of the anatomical positional relationship or results of the recognition processing of tomographic images adjacent to the correction position, and the correction information, and corrects the result of the recognition processing of the incorrectly recognized tomographic image to the correct recognition result.
