Patent ID: 8582856

Claim:
An image processing apparatus comprising: an acquisition unit configured to acquire a tomographic image of the human body in a first body position and to acquire a first three-dimensional image of the human body in a second body position, the tomographic image being captured by a first image capturing apparatus and the first three-dimensional image being captured by a second image capturing apparatus; a first generation unit configured to generate deformation data indicating a deformation of the first three-dimensional image from the second body position to the first body position; a second generation unit configured to generate a first cross-sectional image of the first three-dimensional image, and a second cross-sectional image based on the deformation data, wherein a position and a posture of the first cross-sectional image, the second cross-sectional image and the tomographic image correspond to each other; and a control unit configured to control a display unit to display the first cross-sectional image, the second cross-sectional image and the tomographic image, so that the first cross-sectional image and the second cross-sectional image are arranged in a mirror image relationship.
