    摘要： A technique for rendering a deformable volume includes acquiring 3D images of a deformable volume including an object during phases of a deformation motion. The 3D images include voxels, a portion of which move from original coordinate locations during a primary phase to deformed coordinate locations during each subsequent phase of the deformation motion. Deformation matrixes each based upon one of the 3D images during a different one of the phases are generated. The deformation matrixes each include transformation vectors describing how to return the voxels from their deformed coordination locations to their original coordinate locations of the primary phase. A sub-phase 3D image of the deformable volume between consecutive phases is generated by interpolating between the transformation vectors of the consecutive phases associated with a given coordinate location within the deformable volume and retrieving voxel data from a primary 3D image at voxel locations referenced by interpolated transformation vectors.

    摘要： A method and system are presented for direct volume rendering of a deformable volume dataset that represent an object in motion. An original 3D image dataset of the object is acquired at an initial stage of the motion, and segmented. Deformed 3D image datasets of the object are acquired at subsequent stages of the motion. Deformation matrices are computed between the segmented original 3D image dataset and the deformed 3D image datasets. A plurality of deformed mesh patches are generated based on the deformation matrices. 2D textures are generated by dynamically sampling the segmented 3D image dataset, and applied to the deformed mesh patches. The textured deformed mesh patches are evaluated, blended, and composited to generate one or more volume-rendered images of the object in motion.
