Abstract
In order to prevent color bleeding, a method of volume rendering a three-dimensional (3D) dataset includes identifying, by a processor, a mask that defines a segmented volume within the 3D dataset. The processor identifies a position within the 3D dataset at or adjacent to a boundary defined by the mask, identifies a plurality of voxels within the 3D dataset that are adjacent to the identified position within the 3D dataset, and determine, for each voxel of the plurality of voxels, whether the respective voxel is inside or outside of the identified mask. The processor determines, for each voxel of the plurality of voxels, a weight for the respective voxel based on the determination of whether the respective voxel is inside or outside of the identified mask. The processor determines a voxel value for the identified position based on the determined weights and voxel values for the plurality of voxels, respectively.
