Claim:
1. A detection apparatus for detecting the position of a boundary between a first part and a second part of a subject, the detection apparatus comprising: a pixel extraction unit for extracting a plurality of candidate pixels acting as candidates for a pixel situated on the boundary on the basis of image data of a first section crossing the first part and the second part; and a pixel specification unit for specifying the pixel situated on the boundary from within the plurality of candidate pixels by using an identifier which has been prepared by using an algorithm of machine learning; wherein the pixel specification unit narrows down candidate pixels which are high in possibility that they are situated on the boundary from within the plurality of candidate pixels, and specifies the pixel which is situated on the boundary from within the narrowed-down candidate pixels by using the identifier.
