Method, system, and computer software product for feature-based correlation of lesions from multiple images
First Claim
Patent Images
1. A computer-implemented method for correlating medical images, comprising:
- obtaining first image data representative of a first medical image including a first abnormality;
obtaining second image data representative of a second medical image including a second abnormality;
determining at least one feature value for each of the first and second abnormalities using the first and second image data;
calculating, based on the determined feature values, a likelihood value indicative of a likelihood that the first and second abnormalities are a same abnormality; and
outputting the determined likelihood value,wherein the step of obtaining the first image data comprises obtaining first image data representative of the first medical image derived using a first modality, the first modality being one of mammography, sonography, and magnetic resonance imaging; and
the step of obtaining the second image data comprises obtaining second image data representative of the second medical image derived using a second modality different from the first modality.

11. A system for correlating medical images, comprising:
-
a mechanism configured to obtain first image data representative of a first medical image including a first abnormality; a mechanism configured to obtain second image data representative of a second medical image including a second abnormality; a mechanism configured to determine at least one feature value for each of the first and second abnormalities using the first and second image data; a mechanism configured to calculate, based on the determined feature values, a likelihood value indicative of a likelihood that the first and second abnormalities are a same abnormality; and a mechanism configured to output the determined likelihood value, wherein the mechanism configured to obtain the first image data comprises a mechanism configured to obtain first image data representative of the first medical image using a first modality, the first modality being one of mammography, sonography, and magnetic resonance imaging; and the mechanism configured to obtain the second image data comprises a mechanism configured to obtain second image data representative of the second medical image using a second modality different from the first modality. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A computer program product which stores, on a computer-readable medium, instructions for execution on a computer system, which when executed by the computer system, causes the computer system to perform the steps of:
-
obtaining first image data representative of a first medical image including a first abnormality; obtaining second image data representative of a second medical image including a second abnormality; determining at least one feature value for each of the first and second abnormalities using the first and second image data; calculating, based on the determined feature values, a likelihood value indicative of a likelihood that the first and second abnormalities are a same abnormality; and outputting the determined likelihood values, wherein the step of obtaining the first image data comprises obtaining first image data representative of the first medical image using a first modality, the first modality being one of mammography, sonography, and magnetic resonance imaging; and the step of obtaining the second image data comprises obtaining second image data representative of the second medical image using a second modality different from the first modality. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
