Abstract

This invention relates to a method and system for remotely monitoring computer-aided detection (CAD) system processing status. In film-based CAD systems digital images are created by a film digitizer, which is typically loaded with 50 or 100 films. Occasionally, film feeding errors occur which halt the digitization. This invention provides a method and system for detecting the stoppage and for notifying an operator who is not in the vicinity of the digitizer. Notification is accomplished by a variety of methods including pager, telephone, cell phone, and mobile computing devices. In addition to notification of stoppages, the operator may choose to be notified when a certain number of films remain to be processed. This allows the digitizer to be loaded with additional films before the CAD system completes processing of the originally loaded set of films. System efficiency is increased by eliminating idle intervals where the CAD system is stopped awaiting input data.

Claims

1. A method for providing remote monitoring of status information to a film-based CAD system user comprising:

providing a CAD system with a film digitizer;

providing films to be processed to the film digitizer;

performing a processing operation on the films;

identifying a status change in the digitizer during the processing operation; and

transmitting notification of the status change to a user located remotely from the digitizer.

2. The method of claim 1 wherein the step of identifying a status change comprises identifying a delay in digitizing a film.

3. The method of claim 2 wherein the step of identifying a delay in digitizing a film comprises initiating a timing process at substantially the same moment as a process of digitizing a film begins and identifying a condition where processing of the film is not complete and the timing process has timed out.

4. The method of claim 2 including the step of the user transmitting a command to the CAD system from a remote location to continue processing of the films after receiving notification of the status change.

5. The method of claim 1 wherein the step of identifying a status change comprises identifying completion of a predetermined digitization operation.

6. The method of claim 5 wherein the completion of a predetermined digitization operation comprises completing digitization of the last case in a group of cases to be digitized.

7. The method of claim 5 including the step of the user inputting a request to the CAD system to be notified upon completion of the predetermined digitization operation.

8. The method of claim 1 wherein the step of identifying a status change comprises completion of a processing operation for a predetermined patient.

9. The method of claim 1 wherein the step of transmitting notification includes transmitting notification through a telephonic device.

10. The method of claim 9 wherein the telephonic device comprises a cellular telephone.

11. The method of claim 9 including the step of the user contacting the CAD system and obtaining additional information relating to the status change from the CAD system upon receiving notification of the status change.

12. The method of claim 11 including the step of the user transmitting a command via the telephone to the CAD system to take a corrective action for processing of the films after receiving notification of the status change.

13. The method of claim 1 wherein the step of transmitting notification includes transmitting notification through a paging device.

14. The method of claim 1 wherein the step of transmitting notification includes transmitting notification through a wireless connection to a mobile computing device.

15. The method of claim 14 wherein the notification comprises an electronic mail message.

16. The method of claim 14 wherein the step of transmitting notification further comprises displaying a message box on a screen of the mobile computing device.

17. The method of claim 1 wherein the step of transmitting notification includes transmitting notification to a monitor located remotely from the digitizer.

18. The method of claim 17 wherein the notification comprises an electronic mail message.

19. The method of claim 17 wherein the step of transmitting notification further comprises displaying a message box on the monitor.

20. The method of claim 1 wherein the step of transmitting notification comprises the CAD system accessing a configuration file containing information including user specific information.

21. The method of claim 20 wherein the user specific information includes phone numbers and predetermined user notification delivery preferences.

22. A method for operating a digitizer comprising:

providing a CAD system, the CAD system including a film digitizer and a user specific configuration file having information for initiating contact with a user;

providing films to be processed to the film digitizer;

performing a processing operation on the films;

identifying a status change in the digitizer during the processing operation; and

transmitting notification of the status change to a user located remotely from the digitizer.

23. The method of claim 22 wherein the step of identifying a status change comprises identifying a delay in digitizing a film.

24. The method of claim 22 wherein the step of transmitting notification comprises automatically initiating contact with the user.

25. The method of claim 24 wherein the step of automatically initiating contact with the user comprises the CAD system accessing a configuration file containing information including user specific information.

26. A method for providing remote monitoring of status information to a film-based CAD system user comprising:

providing a CAD system with a film digitizer;

providing films to be processed to the film digitizer;

performing a processing operation on the films;

identifying a status change in the digitizer during the processing operation; and

initiating contact with a user located remotely from the digitizer in response to the identification of a status change.

27. The method of claim 26 wherein the step of automatically initiating contact with the user comprises the CAD system accessing a configuration file containing information including user specific information.

28. A method for providing remote monitoring of status information to a CAD system user comprising:

providing input imagery to the CAD system;

performing a processing operation on the input imagery;

identifying a status change in the processing operation; and

transmitting notification of the status change to a user located remotely from the CAD system.

29. The method of claim 28 wherein the step of transmitting notification comprises automatically initiating contact with the user.

30. The method of claim 29 wherein the step of automatically initiating contact with the user comprises the CAD system accessing a configuration file containing information including user specific information.

31. The method of claim 30 wherein the user specific information comprises at least an internet access address or phone number for the user to receive an automatically generated message from the system.
