FIELD: medicine; image forming apparatus.SUBSTANCE: device includes memory which stores a medical intensity image to be segmented; one or more processors programmed to apply a pre-segmentation algorithm to intensity image to estimate a boundary of a target volume and to enlarge said estimated boundary to ensure inclusion of said target volume in said enlarged estimated boundary; operate on intensity image within said enlarged estimated boundary with an enhancement filter based on a pool of features to generate an enhanced image which differentiates target volume from neighboring tissue, wherein enhanced image is a three-dimensional image including a three-dimensional array of voxels, a value of each voxel representing a probability that each voxel belongs to target volume; memory for storing enhanced image.EFFECT: high accuracy of image segmentation.7 cl, 8 dwg |
