Abstract

A method and system for analyzing and retrieving tissue abnormality tracking data, providing a tool for a radiologist that includes a report summarizing the statistical frequency of diagnosed patients, both locally and nationally, with tissue region-of-interest classifications similar to the tissue images taken of the anatomy of an individual patient. In one embodiment, a computer aided diagnostic program can suggest region-of-interest attributes and classifications for user review. In one embodiment, user can select a seed area for computer aided diagnostic program analysis, the CAD analysis can suggest region-of-interest attributes and classifications. In yet another embodiment, the region-of-interest abnormality attributes suggested by the computer aided diagnostic program can be stored and compared with the user selected abnormality attributes and classifications. In one embodiment the images are of human breast tissue.

a profiler display configured to present statistical information related to a comparison of the automated categorization with a database of existing categorizations of a plurality of existing breast tissue images, each of the plurality of existing breast tissue images having been diagnosed;

and

a processing engine including a computer aided diagnosis (CAD) tool configured to identify the at least one region of interest in the breast tissue image, to provide the automated categorization of the region of interest, to present the automated categorization of the region of interest via the graphical user interface, and configured to dynamically update the profiler display based on a change in one or more of the plurality of possible characteristics and the unique alphanumeric value associated with the changed characteristic of the region of interest.

2. The system of claim 1, wherein the breast tissue image is selected from the group consisting of an X-ray image, a CT image, an MRI image, an ultrasound image, and a pathology image.

3. The system of claim 1, wherein each of the plurality of existing breast tissue images is cataloged in the database according to a characteristic of the breast tissue image.

4. The system of claim 1, wherein the plurality of possible characteristics from the predetermined medical lexicon includes an abnormality type, size, and profile.

5. The system of claim 1, wherein the computer aided diagnosis (CAD) tool is further configured to identify the plurality of possible characteristics from the predetermined medical lexicon of an abnormality depicted in the at least one region of interest.

6. The system of claim 1, wherein the computer aided diagnosis (CAD) tool is further configured to identify the at least one region of interest in the breast tissue image based on a user selection of a portion of the breast tissue image within the region of interest depicted in the breast tissue image.

7. The system of claim 1, wherein the computer aided diagnosis (CAD) tool is further configured to identify the at least one region of interest in the breast tissue image based on a user selection of a portion of the breast tissue image containing the region of interest depicted in the breast tissue image.

8. The system of claim 1, further comprising an interface to receive the change in one or more of the plurality of possible characteristics from the predetermined medical lexicon of the region of interest.

9. The system of claim 8, wherein the processing engine is operable to compare the automated categorization and the change in one or more of the plurality of possible characteristics from the predetermined medical lexicon of the region of interest.

10. system of claim 9, wherein an algorithm of the CAD tool is updated based on the comparison of the CAD automated categorization with the change in one or more of the plurality of possible characteristics from the predetermined medical lexicon.

11. The system of claim 8, wherein the processing engine is operable to compare the CAD automated categorization with pathological data related to a particular region of interest.

12. A method for managing patient mammography data comprising:

obtaining a plurality of breast tissue images selected from the group consisting of an X-ray image, a CT image, an MRI image, an ultrasound image, and a pathology image;

identifying a region of interest in at least one of the plurality of breast tissue images;

obtaining, from a computer aided diagnosis (CAD) tool, a categorization of a breast tissue abnormality in the region of interest according to an established predetermined medical lexicon, the predetermined medical lexicon including a plurality of lexicon descriptors, wherein each of the plurality of lexicon descriptors in the predetermined medical lexicon is associated with a unique alphanumeric value;

presenting the categorization of the breast tissue abnormality in the region of interest to a user;

receiving a confirmation of the categorization from the user;

associating the confirmed categorization with the region of interest;

comparing the confirmed categorization of the region of interest with a database of existing categorizations of a plurality of existing breast tissue images, each of the plurality of existing breast tissue images having been diagnosed;

presenting a profiler display comprising statistical information related to a comparison of the confirmed categorization with the database of existing categorizations; and

dynamically updating the profiler display based on a modification in one or more of the plurality of lexicon descriptors and the unique alphanumeric value associated with the modified lexicon descriptor for the region of interest.

13. The method of claim 12, further comprising:

receiving the modification of the categorization from the user.

14. The method of claim 12,

wherein the profiler display comprises a diagnostic indicator comprising a number of instances of the categorization within the database of existing categorizations, a number of diagnoses of malignant abnormalities for the categorization among the existing categorizations, and a number of diagnoses of benign abnormalities for the categorization among the existing categorizations.

15. The method of claim 14, further comprising:

updating the diagnostic indicator based on a comparison of the confirmed categorization and the existing categorizations.

16. The method of claim 15, further comprising:

comparing the confirmed categorization with the computer aided diagnosis (CAD) categorization for the same region of interest.

17. The method of claim 12, wherein the database of existing categorizations includes an identified region of interest in each of a plurality of breast tissue images, and wherein each region of interest is associated with one of either a malignant or a benign diagnosis.

18. The method of claim 17, further comprising:

comparing the associated malignant or benign diagnosis of a region of interest in the database with a computer aided diagnosis (CAD) of the one of the plurality of breast tissue images associated with the region of interest.

19. A method for managing patient medical data comprising:
