Abstract

According to one embodiment, a schema storage unit stores a reference schema that schematically expresses the internal structure of a diagnosis target blood vessel concerning the reference section of the diagnosis target blood vessel. A schema processing unit automatically generates a schema concerning a section crossing the reference section of the diagnosis target blood vessel by image processing based on the reference schema.
