Abstract

The invention includes a method including the steps of obtaining a plurality of images, each of the images in the plurality having at least one corresponding region, generating a merged image, the merged image also having the corresponding region. The step of generating includes selecting an image source from the plurality of images to source image data for the corresponding region in the merged image by comparing attributes of the corresponding regions of the plurality of images to identify the image source having preferred attributes.

First claim

What is claimed is:

1. A method for processing breast image data, the method comprising:
obtaining a plurality of images of a breast, wherein each image of the plurality of images comprises a plurality of image regions;
applying a CAD algorithm to each image of the plurality of images;
identifying a first image region in a first image of the plurality of images;
identifying a second image region in a second image of the plurality of images;
comparing the first image region to the second image region;
based at least in part on applying the CAD algorithm and comparing the first image region to the second image region, selecting only one of the first image region and the second image region;
generating a synthesized 2D mammography image of the breast, wherein the synthesized 2D mammography image comprises the selected first image region or the selected second image region; and
displaying the synthesized 2D mammography image.

2. The method of claim 1 , wherein identifying the first image region comprises identifying a boundary of the first image region by comparing at least one pixel in the first image to at least one pixel in the second image.

3. The method of claim 1 , wherein applying the CAD algorithm comprises detecting a feature in at least one image of the plurality of images.

4. The method of claim 3 , wherein applying the CAD algorithm comprises assigning at least one of a value, a weight, and a threshold to at least one pixel in at least one image of the plurality of images.

5. The method of claim 1 , wherein the first image region substantially corresponds to the second image region.

6. The method of claim 1 , further comprising storing a source region, wherein the source region corresponds to one of the selected first image region or the second image region.

7. The method of claim 6 , further comprising displaying the source region.

8. The method of claim 7 , wherein displaying the source region comprises displaying one of the first image and the second image.

9. The method of claim 1 , further comprising determining a display data of the first image and the second image, wherein the display data comprises a high pixel value, a low pixel value, a threshold value, and a weight.

10. The method of claim 1 , wherein the synthesized 2D mammography image of the breast comprises at least one region selected from each of a plurality of the plurality of images.

11. A method for processing breast image data, the method comprising:
obtaining a plurality of images of a breast, wherein each image of the plurality of images comprises a plurality of image regions;
applying a CAD algorithm to each image of the plurality of images;
based at least in part on applying the CAD algorithm, identifying features within respective corresponding image regions of each of the plurality of images;
generating a synthesized 2D mammography image of the breast, wherein the synthesized 2D mammography image comprises the features identified within the respective corresponding image regions of each of the plurality of images;
displaying the synthesized 2D mammography image; and
displaying a visual indicator of a distribution within the breast of the features identified within the respective corresponding image regions of each of the plurality of images.

12. The method of claim 11 , wherein the respective corresponding image regions of each of the plurality of images comprise regions in the plurality of images that substantially overlap.

13. The method of claim 11 , wherein the visual indicator comprises a histogram comprising depth data of the features identified within the respective corresponding image regions of each of the plurality of images.

14. The method of claim 11 , wherein the histogram comprises a first line and at least one second line disposed substantially orthogonal to the first line.

15. The method of claim 14 , wherein the at least one second line comprises a plurality of second lines.

16. The method of claim 11 , wherein the visual indicator comprises a graphical indicator.

17. The method of claim 11 , further comprising displaying a synthesized region of the synthesized 2D mammography image.

18. The method of claim 11 , wherein the visual indicator comprises an outline of the respective corresponding regions on the synthesized 2D mammography image.

19. The method of claim 11 , further comprising storing a source region, wherein the source region corresponds to one of a first image region of a first image of the plurality of images or a selected image region of a second image of the plurality of images.

20. The method of claim 19 , further comprising displaying the source region.
