System and method for gradient assisted non-connected automatic Region (GANAR) analysis
First Claim
1. A method for programming operation of a radiation therapy system to deliver radiation therapy to a subject, the method comprising:
- Acquiring medical images of the subject including functional information and anatomical information about the subject;
Acquiring texture feature images;
using the medical images and the texture feature images, determining a plurality of segmentation surfaces by minimizing a relationship between a region growing algorithm that selects a region of interest (ROI) to determine a given segmentation surface and cost function for evaluating the given segmentation surface;
Synthesizing the plurality of segmentation surfaces into a segmentation report; and
using information from the segmentation report to program operation of the radiation therapy system for a delivery of radiation therapy to the subject.

Abstract
A system and method for analyzing medical images of a subject includes acquiring the medical images of the subject and texture images. A computer system determines, using the medical images and the texture feature images, a plurality of segmentation surfaces by iteratively adjusting a relationship between a region growing algorithm that selects a region of interest (ROI) to determine a given segmentation surface and cost function for evaluating the given segmentation surface. The computer system generates a report using the plurality of segmentation surfaces indicating at least boundaries between anatomical structures with functional differences in the medical images.
