Abstract: PURPOSE: A 3D volume-plan coupled image generating method is provided to obtain an image in which a planer image of a body part is coupled with related volumetric portions, thereby providing images more precise and easier to understand in the medical fields. CONSTITUTION: A method for generating 3D volume-plan coupled images includes a volume rendering step of shearing an original image data with respect to an object by the shear-warp algorithm to obtain volume data on the sheared plan and generating an intermediate volume image formed on an intermediate image plan by mixing(S11), an MPR(Multi-Planer Reconstruction) image extracting step of generating topographical images with respect to a selected portion by MPR and carrying out affine transform proper to the intermediate image plan, an image coupling step of coupling the intermediate volume image with the MPR image(S12), and a volume-plan coupled image generating step of warping the intermediate volume image-MPR coupled image for generating a final volume-plan coupled image with respect to the object(S28,S29).

Abstract: PURPOSE: A method for obtaining three-dimensional image data and an apparatus thereof are provided to show a brain activation area and the route of a fiber texture, at the same time, together with an anatomical image. CONSTITUTION: A method for obtaining three-dimensional image data comprises the following steps of: dividing a brain image of the human generated by an image acquiring means into a gray matter and a white matter; re-configuring the cortex surface of the gray matter into a three-dimensional image through a process of adjusting the transparency; and merging the re-configured three-dimensional image with analysis data measured through a brain function magnetic resonance imaging device(fMRI).
