Segmentation in medical images
First Claim
1. A method of segmenting information to identify organ nodules in a series of digital images comprising:
- forming from the digital images a series of reduced resolution images having a spatial resolution that is coarser than that of said digital images;
processing the reduced resolution images to identify a reduced resolution body region and a reduced resolution background region;
using the identification of the reduced resolution body region and the reduced resolution background region to identify a body region and a background region in the digital images;
processing an organ region in the digital images to identify a boundary of an organ; and
processing the digital images to identify a region of interest in the organ.

Abstract
A method and system of volume segmentation is disclosed. To address throughput speed and accuracy requirements, the segmentation is divided into two stages: presegmentation and detailed segmentation. In presegmentation, a digital image volume is processed to identify anatomical structures from image backgrounds in a gross manner possibly at reduced image resolution. Detailed segmentation then involves refining and segmenting further the fine details within the anatomical structures identified by presegmentation. One result of the overall volume segmentation algorithm is a volume in which segmented regions of interest, such as nodules, are identified.
