Abstract
A medical image processing apparatus having an image conversion section including a coordinate-system converting section for converting an image in an orthogonal coordinate system to an image in a polar coordinate system, for geometrically converting a medical image of a tubular part in vivo picked up and obtained by the coordinate-system converting section; a squamocolumnar junction detecting section for detecting a squamocolumnar junction that is a junction between a squamous epithelium and a columnar epithelium on the image of the polar coordinate system; and an analyzing section for comparing an evaluation value for a feature value determined for the detected squamocolumnar junction and a predetermined reference value and calculating an analysis result.
