Abstract: A first 3D image and a second 3D image imaged a target organ in different phases of respiration are acquired. A 3D deformation model of the target organ which is stored in advance and represents nonlinear 3D deformation of the target organ due to respiration, and which has been generated based on information about movement of the target organ due to respiration of plural patients, is read. The positions of pixels on the second 3D image representing the same positions on the target organ as plural sampled pixels in a target organ region on the first 3D image are estimated using displacement due to changes in phase of points on the 3D deformation model corresponding to the positions on the target organ represented by the pixels. Non-rigid alignment is performed between the first 3D image and the second 3D image using the estimated positions of the pixels.

Abstract: A three-dimensional common coordinate system is defined and a first correspondence relationship between each pixel of a first three-dimensional image which has at least a portion of a human body as a subject and coordinates on the common coordinate system is set. A second three-dimensional image which has at least a portion of the human body as a subject that at least partially overlaps the subject in the first three-dimensional image is aligned with the first three-dimensional image to calculate a correspondence relationship between pixels of the first three-dimensional image and the second three-dimensional image. A second correspondence relationship between each pixel of the second three-dimensional image and coordinates on the common coordinate system is calculated on the basis of the calculated correspondence relationship and the set first correspondence relationship. The first correspondence relationship and the second correspondence relationship are stored.

Abstract: An intervertebral foramen position detection unit detects positions of intervertebral foramens in a three-dimensional medical image including plural vertebrae. In this case, for example, a feature value representing a likelihood of an intervertebral foramen is used. A vertebra identification unit identifies each of the plural vertebrae by using the detected positions of the intervertebral foramens, respectively.
