Method, system and computer readable medium for an intelligent search workstation for computer assisted interpretation of medical images
First Claim
1. In a user interface of a computer-aided detection (CAD) system, a method for facilitating user diagnosis of a detected lesion in an x-ray mammogram, comprising:
- displaying a first image of the detected lesion to the user;
selecting a plurality of reference images from a reference lesion database based on similarity to said detected lesion with respect to at least one computed feature characteristic; and
displaying said plurality of reference images near the first image, each reference image comprising a lesion with a known diagnosis and being visibly marked according to said known diagnosis.

Abstract
A method, system and computer readable medium for an intelligent search display into which an automated computerized image analysis has been incorporated. Upon viewing an unknown mammographic case, the display shows both the computer classification output as well as images of lesions with known diagnoses (e.g., malignant vs. benign) and similar computer-extracted features. The similarity index used in the search can be chosen by the radiologist to be based on a single feature, multiple features, or on the computer estimate of the likelihood of malignancy. Specifically the system includes the calculation of features of images in a known database, calculation of features of an unknown case, calculation of a similarity index, display of the known cases along the probability distribution curves at which the unknown case exists. Techniques include novel developments and implementations of computer-extracted features for similarity calculation and novel methods for the display of the unknown case amongst known cases with and without the computer-determined diagnoses.

7. In a user interface of a computer-aided detection (CAD) system, a method for facilitating user diagnosis of a detected lesion in an x-ray mammogram, comprising:
-
receiving a selection of the detected lesion on a first display; displaying a first image of the detected lesion on a second display; and displaying a plurality of reference images on the second display near the first image, each reference image based on a similarity to said detected lesion with respect to at least one computed feature characteristic and comprising a lesion with a known diagnosis and being visibly marked according to said known diagnosis, including displaying said reference images sized smaller than said first image and simultaneously with display of said first image on said second display. - View Dependent Claims (8, 9, 10, 11)
