Abstract

A method and system for grouping images generated from a Tomosynthesis process is disclosed herein. The Method of grouping series of images obtained from a tomosynthesis process comprises generating an identifier during each imaging stage and writing the identifier to the DICOM header of the images generated during each imaging stage. The images having the same series unique identifier is displayed using a same series number. The imaging stages include pre-shot, acquisition, reconstruction and retro-reconstruction. A tomosynthesis system using the method of grouping is also disclosed.

Claims

1. A method of grouping series of images generated from a tomosynthesis process comprising the steps of:

(a) generating an identifier during a plurality of imaging stages;

(b) writing the identifier to a DICOM header of a plurality of images; and

(c) displaying images grouped based on the identifier.

2. A method of grouping series of images as claimed in claim 1, wherein the plurality of imaging stages include an image-generating stage including a pre-shot and acquisition stage, and an image-processing stage including a reconstruction and retro-reconstruction stage.

3. A method of grouping series of images as claimed in claim 1, wherein the images include raw images and processed images, the raw images include an image acquired during pre-shot and tomo projections acquired during acquisition, and the processed images include a pre-shot image and tomo slices generated during reconstruction and retro-reconstruction.

4. A method of grouping series of images as claimed in claim 1, wherein the step of generating an identifier comprises generating a series unique identifier during a plurality of imaging stages corresponding to each imaging stage.

5. A method of grouping series of images as claimed in claim 3, wherein the series unique identifier is a DICOM compliant number.

6. A method of grouping series of images as claimed in claim 1, wherein the step of writing the identifier to a DICOM header of the images comprises updating the DICOM header of plurality of images during each imaging stage with corresponding identifier.

7. A method of grouping series of images as claimed in claim 1, wherein the step of displaying further comprises generating a series number corresponding to the series unique identifier.

8. A method of grouping series of images as claimed in claim 7, further comprising displaying the grouped images with the series number, after each imaging stage.

9. A method of grouping series of images as claimed in claim 6, wherein the DICOM header of each image further includes series number, date and time of imaging stages.

10. A tomosynthesis system comprising,

an imager for providing images;

a computer coupled to the imager for grouping the images during a plurality of imaging stages;

wherein the grouping is based on an identifier generated during the plurality of imaging stages.

11. A tomosynthesis system as claimed in claim 10, wherein the plurality of imaging stages comprises an image generating-stage including pre-shot and acquisition stage and an image-processing stage including reconstruction stage and retro-reconstruction stage.

12. A tomosynthesis system as claimed in claim 10, wherein the computer comprises a processor for generating the series unique identifier during each imaging stage, and the series unique identifier includes a DICOM compliant number.

13. A tomosynthesis system as claimed in claim 11, wherein the processor is further configured for writing the identifier to a DICOM header of plurality of images during each imaging stage.

14. A tomosynthesis system as claimed in claim 11, wherein the processor is further configured for generating a series number, corresponding to the series unique identification number for displaying the grouped images.

15. A tomosynthesis system as claimed in claim 10, further comprises a display for displaying grouped images with series number after each imaging stage.

16. A tomosynthesis system as claimed in claim 10, further comprises a user interface for interpreting the identifier from the DICOM header of the images.

17. A tomosynthesis system as claimed in claim 10, wherein the tomosynthesis system includes Mammographic Tomosynthesis system and Radiographiy Tomosynthesis system.

18. A computer program, provided on one or more computer readable media, for grouping series of images obtained from a tomosynthesis process comprising:

a routine for generating an identifier in a plurality of imaging stages;

a routine for writing the identifier to a DICOM header of the images; and

a routine for displaying images grouped based on the identifier.

19. A computer program as claimed in claim 18, wherein the plurality of imaging stages comprise an image-generating stage including a pre-shot and acquisition stage and an image processing stage including reconstruction and retro-reconstruction stage.

20. A computer program as claimed in claim 18, wherein the routine for generating an identifier comprises a routine for generating a DICOM compliant series unique identifier, during each imaging stage.

21. A computer program as claimed in claim 18, wherein the routine for writing the identifier to a DICOM header of the images comprises a routine for updating the DICOM header of plurality of images during plurality of imaging stages with corresponding series unique identifier.

22. A computer program as claimed in claim 18, wherein the routine for displaying the grouped images comprising generating a series number for displaying the images grouped after each imaging stage, based on the series unique identifier.
