Method and system for analysing tissue from images

摘要

Disclosed is a method of analyzing tissue from an image comprising providing an electronic image of tissue (100, 400, 450, 600, 800, 1100), determining a reference value from the image (1070, 1170, 1270), establishing an hint representation (500,700) of the image, and using the hint representation in analysis of the tissue to quantify the breast and compute a calibration error. Also disclosed is a system which runs an inner breast edge detection algorithm (1310) on the electronic image to detect the inner breast edge on the image (1315), and refined the inner breast edge location (1340) if a calibration error is not acceptable (1324). Also disclosed is automatic estimation of breast composition and temporal analysis of images.

1. A method of analyzing tissue from a breast image utilizing a system for analysis of tissue from a breast image, comprising:
operating an electronic breast imager to provide an electronic image of breast tissue (100,400,450,600,800,1100); operating a histogram generating device to generate a histogram (500, 700) representative of said electronic image of said breast tissue; running an inner breast detection 1310) on a histogram from an inner breast edge locating device to detect an inner breast edge of said breast tissue and to produce an inner breast edge location (1070,1170,1270,1315); determining a reference spot on said image of breast tissue using said inner breast edge location with a reference spot determining device; determining a calibration error with a calibration error determining device, and determining if said calibration error of said inner breast edge location is acceptable (1322); and determining, with a breast density analyzing device, whether said image of breast tissue is of dense breast tissue, and if said image of breast tissue is of dense breast tissue, determining a new reference spot with said reference spot determining device.
