Abstract

Claims (29)

1. A method comprising:

providing a server computer including a graphics processing unit, where the server computer:

a) receives a 3-D volumetric image reconstructed from a plurality of measured 2-D projection images;

b) computes three or more generated 2-D projection images based on three or more 3-D volumetric image viewing directions, where a first viewing direction is given by .theta.0, where the first viewing direction is based on user input, where a second viewing direction is given by .theta.1, where .theta.1 is selected according to a periodic continuous mathematical function (v(t)), where v(t)=normalize ({right arrow over (z)}+A sin(ωt{right arrow over (x)})), where normalize (v) is v/lvl, t is time, ω is 2 π f, f is frequency and A is Amplitude, where a third viewing direction is given by .theta.2, where .theta.2 is selected according to the periodic continuous mathematical function; and

c) sends the three or more generated 2-D projection images and a viewing instruction adapted for display to a remote device, where the viewing instruction specifies an order of display of the three or more generated 2-D projection images for display on the remote device.

2. The method of claim 1 , where at least one generated 2-D projection image of the three or more generated 2-D projection images enhance a microcalcification.

3. The method of claim 1 , where at least one generated 2-D projection image of the three or more generated 2-D projection images enhance an obstruction.

4. The method of claim 1 , where at least one generated 2-D projection image of the three or more generated 2-D projection images enhance a tumor.

5. The method of claim 1 , where the 3-D volumetric image is a Digital Breast Tomosynthesis image.

6. The method of claim 1 , where the three or more generated 2-D projection images are displayed as a video.

7. The method of claim 6 , where the video displays a dynamic comparison.

8. The method of claim 1 , where the plurality of measured 2-D projection images are measured from a breast.

9. The method of claim 1 , where the three or more generated 2-D projection images are generated from viewing directions spanning one period of the periodic continuous mathematical function.

10. The method of claim 1 , where the three or more generated 2-D projection images are cached in a memory.

11. A system comprising:

a server digital data processor in communications coupling with a client digital data processor; and

a program, executing on the server digital data processor, the program carrying out the steps comprising:

a) receiving a 3-D volumetric image reconstructed from a plurality of measured 2-D projection images;

b) computing three or more generated 2-D projection images based on three or more 3-D volumetric image viewing directions, where a first viewing direction is given by .theta.0, where .theta.0 is selected based on user input, where a second viewing direction is given by .theta.1, where .theta.1 is selected according to a periodic continuous mathematical function (v(t)), where v(t)=normalize(ź+A sin(ω t {acute over (x)})), where normalize(v) is v/lvl, t is time, ω is 2 π f, f is frequency and A is Amplitude, where a third viewing direction is given by .theta.2, where .theta.2 is selected according to the periodic continuous mathematical function; and

c) sending the three or more generated 2-D projection images and viewing instructions to the client digital data processor, where the viewing instructions specify that the three or more generated 2-D projection images are displayed with one or both increasing .theta. and decreasing .theta.

12. The system of claim 11 , where at least one generated 2-D projection image of the three or more generated 2-D projection images enhance a microcalcification.

13. The system of claim 11 , where at least one generated 2-D projection image of the three or more generated 2-D projection images enhance an obstruction.

14. The system of claim 11 , where at least one generated 2-D projection image of the three or more generated 2-D projection images enhance a tumor.

15. The system of claim 11 , where the 3-D volumetric image is a Digital Breast Tomosynthesis image.

16. The system of claim 11 , where the three or more generated 2-D projection images are displayed as a video.

17. The system of claim 16 , where the video displays a dynamic comparison.

18. The system of claim 11 , where the plurality of measured 2-D projection images are measured from a breast.

19. The system of claim 11 , where the three or more generated 2-D projection images are generated from viewing directions spanning one period of the periodic continuous mathematical function.

20. The system of claim 11 , where the three or more generated 2-D projection images are cached in a memory.
