Patent attributes
Systems and methods for processing colon image data are provided. Image data related to a first ROI may be obtained, wherein the first ROI may include a soft tissue represented by a plurality of voxels, and each voxel may have a voxel value. A first virtual scene may be visualized based on the image data, wherein the first virtual scene may reveal at least one portion of the first ROI. A collision detection may be performed between at least one portion of the first ROI and a virtual object in the first virtual scene. A feedback force may be determined from at least one portion of the first ROI based on the collision detection. At least one of the plurality of voxels corresponding to a second ROI may be determined based on the feedback force, wherein the second ROI may relate to the soft tissue in the first ROI.
