Abstract
A method and apparatus for tracking disease progression as revealed by multiple lesions perform a global optimization to identify corresponding lesions by overlap, for example, after outlines of the lesions have been morphologically dilated. A clustering algorithm addresses the problem of lesions separating into parts or joining together to provide a clear picture of disease progression.
Claims14
An apparatus for assessing treatment of a patient comprising:
- an electronic computer executing a stored program to:
- (a) receive a first and a subsequent, second scan of tissue of the patient revealing diseased tissue at different times with respect to treatment of a patient such as may indicate treatment efficacy;
- (b) perform a registration of the first and second scans;
- (c) identify first lesions in the first scan and second lesions in the second scan;
- (d) measure an overlapping of first regions around and larger than each of the first lesions with second regions around and larger than each of the second lesions;
- (e) match first lesions with second lesions based on overlap between the first and second regions;
- and
- (f) compare changes in lesions as matched between the first and subsequent second scan to provide a report indicating disease progression.
