Abstract

Certain embodiments of the present invention provide a system, method and computer instructions for assessing alertness of an operator of an image review system. In an embodiment, such a system includes: an input module configured to allow alertness data to be input; an alertness assessment module configured to evaluate alertness based on the alertness data; and an output module configured to output information based on the evaluation made by the alertness assessment module. In certain embodiments, the input module may input alertness data from: a three-dimensional coordinate tracking system; a brain wave monitoring device; an eye movement monitoring device; a video recording device; and/or an eye closure monitoring device, for example. In certain embodiments, the alertness assessment module may evaluate alertness data using: a Psychomotor Vigilance Performance Task; the Karolinska Sleepiness Scale; and/or a Visual Analogue Sleepiness Scale, for example.

Claims

1. A system comprising:

a diagnostic image review system configured to display a plurality of images such that each displayed image can be reviewed by an operator for diagnostic purposes;

an input module operably connected to the diagnostic image review system, the input module configured to input alertness data regarding alertness of the operator while the operator reviews each displayed image, the input module and diagnostic image review system configured such that each of the displayed images is associated with alertness data that was input while the image was being displayed by the diagnostic image review system;

an alertness assessment module operably connected to the input module and configured to evaluate said alertness data to identify one or more images that were displayed by the diagnostic image review system while the operator was not sufficiently alert; and

an output module operably connected to the alertness assessment module and configured to output information based on the evaluation made by the alertness assessment module.

2. The system of claim 1, wherein said input module is configured to input data from a three-dimensional coordinate tracking system.

3. The system of claim 1, wherein said input module is configured to input data from at least one of:

a brain wave monitoring device, and an eye movement monitoring device.

4. The system of claim 1, wherein said input module is configured to input data from a video recording device.

5. The system of claim 1, wherein said input module is configured to input data from an eye closure monitoring device.

6. The system of claim 1, wherein said alertness assessment module evaluates alertness data using at least one of:

a psychomotor vigilance performance task;

the Karolinska sleepiness scale; and

a visual analogue sleepiness scale.

7. The system of claim 1, wherein said diagnostic image review system is a picture arching and communicating system workstation.

8. A system comprising:

a diagnostic image review system configured to display a plurality of images such that each displayed image can be reviewed by an operator for diagnostic purposes;

an input module operably connected to the diagnostic image review system, the input module configured to input alertness data regarding alertness of the operator while the operator reviews each displayed image, the input module and diagnostic image review system configured such that each of the displayed images is associated with alertness data that was input while the image was being displayed by the diagnostic image review system;

an alertness assessment module operably connected to the input module and configured to evaluate said alertness data to identify one or more images that were displayed by the diagnostic image review system while the operator was not sufficiently alert, wherein the alertness assessment module is configured to receive alertness data multiple times during the display of each image, and wherein the alertness assessment module is configured to indicate that the operator of the image review system was not sufficiently alert when reviewing a displayed image if any of the alertness data associated with the displayed image indicates that the operator was not sufficiently alert when reviewing the displayed image; and

an output module operably connected to the alertness assessment module and configured to output information based on the evaluation made by the alertness assessment module.

9. The system of claim 8, wherein said input module is configured to input data from a three-dimensional coordinate tracking system.

10. The system of claim 8, wherein said input module is configured to input data from at least one of:

a brain wave monitoring device, and an eye movement monitoring device.

11. The system of claim 8, wherein said input module is configured to input data from a video recording device.

12. The system of claim 8, wherein said input module is configured to input data from an eye closure monitoring device.

13. The system of claim 8, wherein said alertness assessment module evaluates alertness data using at least one of:

a psychomotor vigilance performance task;

the Karolinska sleepiness scale; and

a visual analogue sleepiness scale.

14. The system of claim 8, wherein said diagnostic image review system is a picture arching and communicating system workstation.

15. A system comprising:

a diagnostic image review system configured to display a plurality of images such that each displayed image can be reviewed by an operator for diagnostic purposes;

an input module operably connected to the diagnostic image review system, the input module configured to input alertness data regarding alertness of the operator while the operator reviews each displayed image, the input module and diagnostic image review system configured such that each of the displayed images is associated with alertness data that was input while the image was being displayed by the diagnostic image review system;

an alertness assessment module operably connected to the input module and configured to evaluate said alertness data to identify one or more images that were displayed by the diagnostic image review system while the operator was not sufficiently alert; and

an output module operably connected to the alertness assessment module and configured to output information based on the evaluation made by the alertness assessment module, wherein the output module is configured to output an image identified by the alertness assessment module as being displayed by the diagnostic image review system while the operator was not sufficiently alert such that the output image is redisplayed by the diagnostic image review system.

16. The system of claim 15, wherein said input module is configured to input data from a three-dimensional coordinate tracking system.

17. The system of claim 15, wherein said input module is configured to input data from at least one of:

a brain wave monitoring device, and an eye movement monitoring device.

18. The system of claim 15, wherein said input module is configured to input data from a video recording device.

19. The system of claim 15, wherein said input module is configured to input data from an eye closure monitoring device.

20. The system of claim 15, wherein said alertness assessment module evaluates alertness data using at least one of:

a psychomotor vigilance performance task;

the Karolinska sleepiness scale; and

a visual analogue sleepiness scale.

21. The system of claim 15, wherein said diagnostic image review system is a picture arching and communicating system workstation.
