Title:
MEDICAL IMAGE PROCESSING DEVICE AND MEDICAL IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2008/012988
Kind Code:
A1
Abstract:
A medical image processing device includes: a 3D model estimation unit for estimating a 3D model of a living organ; a detection object region setting unit for setting a detection object region of a lesion having a protrusion shape; a detection object region setting unit for setting a detection object region of the region having the protrusion shape; a shape feature amount calculation unit for calculating a shape feature amount indicating a convex/concave state of each voxel contained in the detection object region; a 3D shape detection unit for detecting a first voxel having a protrusion shape and a second voxel having a concave shape; a swelling shape judging unit which judges that the protrusion shape of the first voxel is not caused by a lesion if the first voxel is near to the second voxel and a voxel group forming a concave portion exists between the first voxel and the second voxel.
