1. A system for segmenting a target organ tumor from an image, comprising:
- a background model builder, wherein the background model builder uses an intensity distribution estimate of voxels in an organ region in an image to build a background model;
a foreground model builder, wherein the foreground model builder uses an intensity distribution estimate of voxels in a target organ tumor to build a first foreground model; and
a tumor region locator, wherein the tumor region locator uses the background model and the first foreground model to segment the target organ tumor to obtain a first segmentation result.

Abstract
A system for segmenting a target organ tumor from an image includes a background model builder, a foreground model builder and a tumor region locator. The background model builder uses an intensity distribution estimate of voxels in an organ region in an image to build a background model. The foreground model builder uses an intensity distribution estimate of voxels in a target organ tumor to build a first foreground model. The tumor region locator uses the background model and the first foreground model to segment the target organ tumor to obtain a first segmentation result.

11. A computer readable medium embodying instructions executed by a processor to perform a method of segmenting an object of interest from a medical image, the method comprising:
-
building a background using a segmentation technique; building a foreground using the background and a block of sample voxel intensities of an object of interest in an image; and segmenting the object of interest in an organ region of the image using the foreground and the background. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
