Image processing apparatus and image processing method

摘要

An extraction unit extracts a centerline of a tubular structure from a volume data set. A generation unit generates a plurality of image data sets concerning a plurality of curved planes based on the volume data set. Each of the curved planes contains the centerline. The plurality of image data sets have a plurality of image lengths respectively and contain a plurality of centerlines respectively. A first specification unit specifies a first image data set or a second image data set from the plurality of image data sets. The first image data set is specified based on the plurality of image lengths of the plurality of image data sets. The second image data set is specified based on gradients of the plurality of centerlines of the plurality of image data sets. A display unit displays the first image or the second image.
