Field of view navigation tracking
A digital pathology system for recording and displaying field of view portions that have been viewed in the context of developing a diagnosis for a pathology case. A whole slide image is presented with shading overlaid on the image illustrating those portions that have been viewed. Portions of the WSI that have received the pathologist's attention at different magnifications are marked with distinguishing hatching.
1. A digital pathology system for recording and displaying field of view portions of a whole slide image comprising:
at least one processor;
a memory in operative connection with the at least one processor;
wherein, responsive to execution of program instructions accessible to the at least one processor, the at least one processor is configured to:
receive input regarding the selection of at least two selected digital specimen images to be viewed in a viewing window;
display the at least two selected digital specimen images, the at least two selected digital specimen images comprising portions of the whole slide image scanned at one or more magnifications;
record a field of view data trail for the at least two selected digital specimen images that were displayed;
map the at least two selected digital specimen images to the whole slide image;
display the location of the at least two selected digital specimen images on the whole slide image; and
display an indicator of the proportion of the whole slide image that has been viewed at each of the one or more magnifications.
2. The system of claim 1 , wherein the at least two selected digital specimen images are displayed in the viewing window one at a time in the order in which they were selected.
3. The system of claim 1 , wherein the at least two selected digital specimen images are stored in the memory.
4. The system of claim 1 , wherein the at least two selected digital specimen images mapped onto the whole slide image are displayed in a tracking viewer.
5. The system of claim 4 , wherein the tracking viewer partially covers the viewing window.
6. The system of claim 4 , wherein all of the at least two selected digital specimen images are displayed in the tracking viewer at the same time.
7. The system of claim 4 , wherein all of the at least two selected digital specimen images are displayed back to back in the order they were selected in order to serve as a training tool.
8. The system of claim 1 , wherein the location of the at least two selected digital specimen images is displayed using semitransparent shading overlaid on the whole slide image.
9. The system of claim 8 , wherein the semitransparent shading varies depending on the magnification used to capture the at least two selected digital specimen images.
10. The system of claim 9 , wherein the shading increases with increasing magnification.
11. The system of claim 9 , wherein the shading comprises different colors for different magnifications.
12. A method of illustrating the portions of a whole slide image that have been evaluated comprising:
receiving input about at least two selected digital specimen images, the selected digital specimen images comprising portions of the whole slide image;
recording a field of view data trail for the at least two selected digital specimen images;
mapping the at least two selected digital specimen images to the whole slide image;
displaying a representation of the portions as semitransparent shaded areas overlaid on the whole slide image; and
displaying an indicator of the proportion of the whole slide image that has been viewed at each of the one or more magnifications.
13. The method of claim 12 , wherein the at least two selected digital specimen images comprise portions of the whole slide image scanned at one or more magnifications.
14. The method of claim 13 , wherein the shading differs depending on the level of magnification.
15. The method of claim 14 , wherein the darkness of the shading increases in correlation with increasing magnification.
16. The method of claim 13 , wherein the semitransparent shading comprises colors corresponding to different magnifications.
17. The method of claim 12 , wherein the step of mapping further comprises calculating the location and size of the shaded area on the whole slide image.
18. The method of claim 12 , wherein the step of displaying the shaded areas is performed sequentially for training purposes.
19. The method of claim 12 , further comprising providing a table that summarizes the proportion of tissue that has been viewed at each magnification level.
20. A computer program product comprising:
a non-transitory computer-readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
computer readable program code configured to display at least two digital specimen images on a display device;
computer readable program code configured to receive input regarding the at least two selected digital specimen images;
computer readable program code configured to record a field of view data trail for the at least two selected digital specimen images; and
computer-readable program code configured to map the at least two selected digital specimen images to a whole slide image, display a representation of the at least two digital specimen images as semitransparent shaded areas overlaid on the whole slide image, and display an indicator of the proportion of the whole slide image that has been viewed at each of the one or more magnifications.
