Abstract

A method for associating a computer aided detection/diagnosis result with an image including the steps of providing one or more digitized images, each image comprising a plurality of intensities corresponding to a domain of points on an N-dimensional grid, performing a computer-aided detection/diagnosis of intensity data of a first image, calculating a hash signature of intensity of a second input image, storing said computer-aided diagnosis results, and storing said hash signature, wherein said hash signature verifies said second image when said second image is displayed with said computer-aided diagnosis result.

Claims

1. A method of associating a computer aided detection/diagnosis result with an image comprising the steps of:

providing one or more digitized images, each image comprising a plurality of intensities corresponding to a domain of points on an N-dimensional grid;

performing a computer-aided detection/diagnosis of intensity data of a first image;

calculating a hash signature of intensity of a second input image;

storing said computer-aided diagnosis results; and

storing said hash signature, wherein said hash signature verifies said second image when said second image is displayed with said computer-aided diagnosis result.

2. The method of claim 1, wherein said second image is not used as input to said computer aided diagnosis.

3. The method of claim 1, wherein said second image is provided as input for said computer-aided detection/diagnosis.

4. The method of claim 1, further comprising storing a locator for said input image with said computer-aided diagnosis results.

5. The method of claim 1, further comprising storing the input image along with said computer-aided diagnosis results.

6. The method of claim 1, wherein calculating a hash signature comprises submitting said input image to a hash function calculator system that calculates said hash signature.

7. The method of claim 6, further comprising submitting identifying information for said input image to said hash function calculator system for calculating said hash signature.

8. The method of claim 7, wherein said identifying information includes one or more of an image locator, a patient'"'"'s name, a patient'"'"'s birth date, a patient'"'"'s gender, a date of patent'"'"'s examination wherein said input image was created, an exam type, and a unique identifier of said input image.

9. The method of claim 1, wherein said computer-aided diagnosis results and said hash signature are stored together in a same file.

18. The computer readable program storage device of claim 1, the method further comprising storing a locator for said input image with said computer-aided diagnosis results.

10. A method of associating a computer aided detection/diagnosis result with an image comprising the steps of:

providing results of a computer aided detection/diagnosis of a first digitized medical image;

providing a hash signature of a second medical image to be displayed with said computer aided detection/diagnosis results;

providing a digitized input image comprising a plurality of intensities corresponding to a domain of points on an N-dimensional grid

calculating a hash signature of said input image; and

comparing the hash signature of said input image with the hash signature read from said computer aided diagnosis results.

11. The method of claim 10 further comprising reading a locator for said input image from said computer aided diagnosis results, and using said locator to locate said input image for calculating said hash signature.

12. The method of claim 10, further comprising, if said hash signatures are equal, displaying said input image with said computer aided diagnosis results.

13. The method of claim 10, further comprising submitting said input image to a hash function calculator system that calculates said hash signature of said input image.

14. The method of claim 10, wherein said second medical image corresponds to said computer aided diagnosis results.

15. A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform the method steps for associating a computer aided detection/diagnosis result with an image said method comprising the steps of:

providing one or more digitized images, each image comprising a plurality of intensities corresponding to a domain of points on an N-dimensional grid;

performing a computer-aided detection/diagnosis of intensity data of a first image;

calculating a hash signature of intensity of a second input image;

storing said computer-aided diagnosis results; and

storing said hash signature, wherein said hash signature verifies said second image when said second image is displayed with said computer-aided diagnosis result.

16. The computer readable program-storage device of claim 15, wherein said second image is not used as input to said computer aided diagnosis.

17. The computer readable program storage device of claim 15, wherein said second image is provided as input for said computer-aided detection/diagnosis.

19. The computer readable program storage device of claim 15, the method further comprising storing the input image along with said computer-aided diagnosis results.

20. The computer readable program storage device of claim 15, wherein calculating a hash signature comprises submitting said input image to a hash function calculator system that calculates said hash signature.

21. The computer readable program storage device of claim 20, the method further comprising submitting identifying information for said input image to said hash function calculator system for calculating said hash signature.

22. The computer readable program storage device of claim 21, wherein said identifying information includes one or more of an image locator, a patient'"'"'s name, a patient'"'"'s birth date, a patient'"'"'s gender, a date of patent'"'"'s examination wherein said input image was created, an exam type, and a unique identifier of said input image.

23. The computer readable program storage device of claim 15, wherein said computer-aided diagnosis results and said hash signature are stored together in a same file.

24. A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform the method steps for associating a computer aided detection/diagnosis result with an image comprising the steps of:

providing results of a computer aided detection/diagnosis of a first digitized medical image;

providing a hash signature of a second medical image to be displayed with said computer aided detection/diagnosis results;

providing a digitized input image comprising a plurality of intensities corresponding to a domain of points on an N-dimensional grid

calculating a hash signature of said input image; and

comparing the hash signature of said input image with the hash signature read from said computer aided diagnosis results.
