Method, system and computer readable medium for an intelligent search workstation for computer assisted interpretation of medical images
First Claim
1. A method for computer assisted interpretation of a medical image, comprising:
- obtaining image data representative of a medical image;
computing at least one feature characteristic of the image data;
comparing the computed feature characteristic to corresponding computed feature characteristics derived from images in a known image data set having known diagnoses;
selecting image data from images of the known image data set having corresponding computed feature characteristics similar to the feature characteristics computed in the computing step; and
displaying the obtained image data, at least one of the selected image data, and a visual indicator associated with the at least one displayed selected image data and which characterizes the known diagnosis of the at least one displayed selected image data.

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.

33. A method for intelligent search of a known database for interpretation of medical images, comprising:
-
generating image data from images derived from patients;
computing feature characteristics of said image data;
comparing said feature characteristics to computer-extracted feature characteristics of images in a known image data set having known diagnoses; and
displaying similar image data derived from different images based on said comparison results, and displaying a visual indicator associated with each displayed image data having known diagnosis and which characterizes the known diagnosis of each displayed image data having known diagnosis.

34. A method for computer-assisted interpretation of a medical image, comprising:
-
obtaining digital image data representative of the medical image;
processing the image data to extract at least one feature characterizing a candidate abnormality;
searching a database of known image data having known diagnoses corresponding to known images having said at least one feature and retrieving known image data having said at least one feature;
comparing said extracted at least one feature with the at least one feature existing in the retrieved known image data to identify known retrieved images having said at least one feature similar to the extracted at least one feature;
displaying image data of a location of the medical image from which said extracted feature was extracted and known image data of a location in a retrieved known image having a similar feature; and
displaying a visual indicator associated with each displayed known image data having known diagnosis and which characterizes the known diagnosis of each displayed known image data. - View Dependent Claims (35)
