Abstract

Systems and methods are disclosed for reviewing multiple images while monitoring a reviewer'"'"'s attentiveness during the review. Systems include an image review system configured to output a series of images to the display and a user attention monitoring system configured to monitor at least one attention parameter for a user during the user'"'"'s review and to generate user attention data based on the at least one attention parameter monitored, wherein the image review system is configured to output the second image to the display if the user attention data indicates sufficient user attentiveness. The image review system may also be configured to generate distraction or review breaks during the review period.

4. The system of claim 1, wherein the attention monitoring system is configured to detect the at least one attention parameter and generate the user attention data independently of the operation of the image review system.

5. The system of claim 1, wherein the image review system is configured to display the first and second images at an image display rate.

6. The system of claim 5, wherein the image review system is configured to receive the image display rate as a user input value.

7. The system of claim 5, wherein the image display rate is measured as a region reviewed per second.

8. The system of claim 5, wherein the image display rate is at least 6 frames per second.

9. The system of claim 5, wherein the image review system is configured to calculate a first image dwell time for the first image and a second image dwell time for the second image based on the image display rate.

10. The system of claim 9, wherein the image review system is configured to calculate the first and second image dwell times based on a scan distance between the first and second images.

11. The system of claim 9, wherein the image review system is configured to display the first image for at least the first image dwell time and the second image for at least the second image dwell time.

12. The system of claim 1, wherein the image review system is configured to display the first image for a first dwell time and the second image for a second dwell time.

13. The system of claim 12, wherein the image review system is configured to access the user attention data generated by the attention monitoring system prior to displaying the second image for a second dwell time.

14. The system of claim 12, wherein the image review system is configured to display the first image for a residual display period prior to displaying the second image.

15. The system of claim 1, wherein the attention monitoring system comprises an attention detection device configured to detect the at least one attention parameter for the user.

16. The system of claim 1, wherein the attention monitoring system comprises a controller configured to generate the user attention data based on the at least one attention parameter detected.

17. The system of claim 1, wherein the attention monitoring system is configured to continuously detect the at least one attention parameter for the user during the multiple image review.

18. The system of claim 1, wherein the image review system is configured to dynamically increase an image display rate for a series of images output to the display based on the user attention data.

19. The system of claim 1, wherein the at least one attention parameter comprises an ocular parameter.

20. The system of claim 19, wherein the ocular parameter comprises eye gaze direction.

21. The system of claim 19, wherein the ocular parameter comprises eye closure.

22. The system of claim 19, wherein the ocular parameter comprises eye movement.

23. The system of claim 1, wherein the at least one attention parameter comprises head position.

24. The system of claim 1, wherein the at least one attention parameter comprises brain wave activity.

25. A system for reviewing multiple images comprising:

a display; and

an image review system configured to output a series of individual images to the display, wherein the image review system is configured to generate at least one distraction break during a user'"'"'s review of the series of image on the display.

26. The system of claim 25, wherein the at least one distraction break comprises stopping the output of the series of individual images to the display.

27. The system of claim 25, wherein the at least one distraction break comprises pausing the output of the series of individual images to the display and presentation of a teaching case to the user.

28. The system of claim 25, wherein the image review system comprises a plurality of stored teaching cases and the image review system is configured to populate a worklist of teaching cases for presentation to the user during the user'"'"'s review of the series of individual images.

29. The system of claim 28, wherein the at least one distraction break comprises presenting at least one teach case from the worklist of teaching cases to the user during the user'"'"'s review of the series of individual images.

30. The system of claim 25 further comprising an attention detector device configured to monitor at least one user attention parameter during the user'"'"'s review of the series of individual images.

31. A method of displaying multiple images comprising:

detecting at least one user attention parameter for a user with a user attention monitoring system;

generating user attention data with the user attention monitoring system based on the at least one user attention parameter;

displaying a first image stored in an image review system on the display; and

electronically accessing the generated user attention data by the image review system prior to displaying a second image stored in the image review system on the display, wherein the second image is displayed on the display if the accessed user attention data indicates sufficient user attentiveness.

32. The method of claim 31 further comprising:

receiving a frame rate; and

calculating a first image dwell duration for the first image and a second image dwell duration based for the second image based on the received frame rate; and
