LESION DETECTION METHOD AND LESION DETECTION PROGRAM

A lesion detection method for a computer to execute a process includes detecting a first lesion region that indicates a certain lesion from each of a plurality of tomographic images obtained by imaging an inside of a human body, by using a first machine learning model that detects a lesion region from an input image that has image data of a two-dimensional space; detecting a second lesion region that indicates the certain lesion from three-dimensional volume data generated based on the plurality of tomographic images, by using a second machine learning model that detects a lesion region from input volume data that has image data of a three-dimensional space; and detecting a third lesion region that indicates the certain lesion from each of the plurality of tomographic images, based on an overlapping state between the first lesion region and the second lesion region.
