Patent Images
1. A method for obtaining a segmented region corresponding to an anatomical organ in a volume image, comprising:
- generating a smoothed image from the volume image;
forming a core segmentation of the volume image according to the smoothed image;
increasing the size of the core segmentation of the volume image to form the segmented region for the anatomical organ according to data obtained from the core segmentation; and
storing data corresponding to the segmented region in a memory.

Abstract
A method for obtaining a segmented region corresponding to an anatomical organ in a volume image generates a smoothed image from the volume image and forms a core segmentation of the volume image according to the smoothed image. The size of the core segmentation of the volume image is increased to form the segmented region for the anatomical organ according to data obtained from the core segmentation. Data corresponding to the segmented region is stored in a memory.

8. A method of segmenting a region corresponding to an anatomical organ of interest in a volume image, the method comprising:
-
receiving a starting point within the volume image and corresponding to a location within the anatomical organ; generating a smoothed image by spatially filtering the volume image; segmenting a core region within the smoothed image based on a predetermined smoothness threshold criterion, wherein the core region includes the starting point; obtaining a low characteristic value and a high characteristic value according to the range of values within the core region; generating an expanded segmented region corresponding to the anatomical organ of interest by expanding the core region according to voxel values within the range defined by the obtained low and high characteristic values; and presenting the expanded segmented region of the anatomical organ of interest on a display. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
