Abstract

A method for synchronizing patient data between at least two independent applications in a distributed environment includes capturing screen information from a display window of a first application client that is displaying a medical image of a patient, analyzing the screen information captured from the first application client display to extract patient identifying information, and synchronizing a display of information of the patient on a second application system display screen with the first application display window using the extracted patient identification information.

Claims

1. A computer implemented method for synchronizing patient data between at least two independent applications in a distributed environment, the method comprising the steps of:

capturing screen information from a display window of a first application client that is displaying a medical image of a patient;

analyzing the screen information captured from the first application client display to extract patient identifying information; and

synchronizing a display of information of said patient on a second application system display screen with said first application display window using said extracted patient identification information.

2. The method of claim 1, wherein analyzing said screen information comprises analyzing text in said screen information for patient identifying information.

3. The method of claim 2, further comprising, when said captured screen information contains no text, presenting identification information for one or more previously identified patients to a user, and soliciting from said user a selection from said one or more previously identified patients.

4. The method of claim 1, wherein analyzing said screen information comprises using a pixel array that is all or part of said patient image being displayed in the first application client display to determine the patient identification information by searching patient data for said pixel array across all images stored in said second application system for a block of pixels identical to said pixel array.

5. The method of claim 1, wherein capturing screen information comprises photographically recording at least part of the first application display with a camera.

6. The method of claim 1, wherein capturing screen information comprises shunting a signal from a display cable to the first application display to a capture device, and recording the screen information with said capture device.

7. The method of claim 1, further comprising transmitting said captured screen information to a second application web server for extraction of the patient identification information.

8. The method of claim 7, wherein said captured screen information is encrypted.

9. The method of claim 7, wherein said captured screen information is compressed.

10. The method of claim 1, further comprising searching for patient identification information in other open windows on the display displaying the first application window.

11. The method of claim 1, further comprising periodically updating said synchronization of said second application system display and said first application display.

12. The method of claim 11, wherein said synchronization is updated based on a state change of at least one of the second application system display and said first application display.

13. The method of claim 1, further comprising designating default locations of patient identification information in the first application client.

14. The method of claim 1, wherein said first application is a picture archiving and communication system (PACS) and said second application is a computer-aided detection diagnosis (CAD) system.

17. The method of claim 1, wherein said first application is a picture archiving and communication system (PACS), and said second application is a computer-aided detection diagnosis (CAD) system.

18. The method of claim 17, further comprising determining whether to display a CAD image based on a user who is logged into the CAD system and rights of this user to view the CAD image.

15. A computer implemented method for synchronizing patient data between at least two independent applications in a distributed environment, the method comprising the steps of:

capturing screen information from a display window of a first application client that is displaying a medical image of a patient;

designating default locations of patient identification information in the first application client; and

analyzing the screen information captured from the first application client display to extract patient identifying information based on knowledge of said default locations of patient identification information.

16. The method of claim 15, further comprising synchronizing a display of information of said patient on a second application system display screen with said first application display window using said extracted patient identification information.

19. A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform the method steps for synchronizing patient data between at least two independent applications in a distributed environment, the method comprising the steps of:

capturing screen information from a display window of a first application client that is displaying a medical image of a patient;

analyzing the screen information captured from the first application client display to extract patient identifying information; and

synchronizing a display of information of said patient on a second application system display screen with said first application display window using said extracted patient identification information.

20. The computer readable program storage device of claim 19, wherein analyzing said screen information comprises analyzing text in said screen information for patient identifying information.

21. The computer readable program storage device of claim 20, the method further comprising, when said captured screen information contains no text, presenting identification information for one or more previously identified patients to a user, and soliciting from said user a selection from said one or more previously identified patients.

22. The computer readable program storage device of claim 19, wherein analyzing said screen information comprises using a pixel array that is all or part of said patient image being displayed in the first application client display to determine the patient identification information by searching patient data for said pixel array across all images stored in said second application system for a block of pixels identical to said pixel array.

23. The computer readable program storage device of claim 19, wherein capturing screen information comprises photographically recording at least part of the first application display with a camera.

24. The computer readable program storage device of claim 19, wherein capturing screen information comprises shunting a signal from a display cable to the first application display to a capture device, and recording the screen information with said capture device.

25. The computer readable program storage device of claim 19, the method further comprising transmitting said captured screen information to a second application web server for extraction of the patient identification information.

26. The computer readable program storage device of claim 25, wherein said captured screen information is encrypted.

27. The computer readable program storage device of claim 25, wherein said captured screen information is compressed.

28. The computer readable program storage device of claim 19, the method further comprising searching for patient identification information in other open windows on the display displaying the first application window.

29. The computer readable program storage device of claim 19, the method further comprising periodically updating said synchronization of said second application system display and said first application display.

30. The computer readable program storage device of claim 29, wherein said synchronization is updated based on a state change of at least one of the second application system display and said first application display.

31. The computer readable program storage device of claim 19, the method further comprising designating default locations of patient identification information in the first application client.

32. The computer readable program storage device of claim 19, wherein said first application is a picture archiving and communication system (PACS) and said second application is a computer-aided detection/diagnosis (CAD) system.
