Abstract

A diagnosis support apparatus comprises an acquiring unit that acquires a plurality of examination data items having different examination dates, a setting unit that sets an extraction condition for examination data items, an extracting unit that extracts, from the plurality of acquired examination data items, examination data items corresponding to the set extraction condition, and a displaying unit that arranges and displays the extracted examination data items, wherein the setting unit sets the extraction condition based on an interval between examination dates of examination data items.

First claim

What is claimed is:

1. An information processing apparatus, comprising:
a hardware processor; and
a memory having instructions stored thereon which, when executed by the hardware processor, cause the information processing apparatus to:
select, in accordance with a user instruction, a plurality of two-dimensional images included in a specific period of time sequence data of a plurality of examination data obtained by analyzing a plurality of tomographic images of an eye obtained by optical coherence tomography at different examination dates, the plurality of examination data including retinal layer thicknesses of the eye; and
control a display device to (a) display the time sequence data in a first display area, to (b) display the selected plurality of two-dimensional images side by side in a second display area, the second display area being different from the first display area and to (c) display a two-dimensional image corresponding to a reference examination data selected from the plurality of examination data, in the second display area.

2. The apparatus according to claim 1 , wherein the instructions, when executed by the hardware processor, further cause the display device to display the selected plurality of two-dimensional images arranged in a time sequence and side by side in a cross direction of the second display area, the first display area and the second display area being arranged side by side in a longitudinal direction of a display screen of the display device.

3. The apparatus according to claim 1 , wherein the instructions, when executed by the hardware processor, further cause the display device to display the selected plurality of two-dimensional images and the time sequence data, arranged up and down.

4. The apparatus according to claim 2 , wherein the instructions, when executed by the hardware processor, further cause the display device to display the selected plurality of two-dimensional images and the time sequence data, arranged up and down.

5. The apparatus according to claim 1 , wherein the plurality of two-dimensional images each comprises an image representing a fundus layer thickness map or a fundus tomogram.

6. The apparatus according to claim 2 , wherein the plurality of two-dimensional images each represents a fundus layer thickness map or a fundus tomogram.

7. The apparatus according to claim 3 , wherein the plurality of two-dimensional images each represents a fundus layer thickness map or a fundus tomogram.

8. An information processing apparatus, comprising:
a hardware processor; and
a memory having instructions stored thereon which, when executed by the hardware processor, cause the information processing apparatus to:
obtain time sequence data of a plurality of examination data obtained by analyzing a plurality of tomographic images of an eye obtained by optical coherence tomography at different examination dates, and a plurality of two-dimensional images of the eye obtained at different examination dates, the plurality of examination data including retinal layer thicknesses of the eye; and
control a display device to (a) display the time sequence data in a first display area, to (b) display the obtained plurality of two-dimensional images in a second display area, the first display area and the second display area being arranged up and down, and to (c) display a two-dimensional image corresponding to a reference examination data selected from the plurality of examination data, in the second display area.

9. The apparatus according to claim 1 , wherein the time sequence data is related to a fundus layer thickness.

10. The apparatus according to claim 2 , wherein the time sequence data is related to a fundus layer thickness.

11. The apparatus according to claim 3 , wherein the time sequence data is related to a fundus layer thickness.

12. The apparatus according to claim 1 , wherein the time sequence data is an analysis image including an analysis map.

13. The apparatus according to claim 8 , wherein the time sequence data is an analysis image including an analysis map.

14. The apparatus according to claim 1 , wherein the time sequence data is a time sequence graph obtained by plotting a plurality of points corresponding to the plurality of examination data in time sequential order.

15. The apparatus according to claim 8 , wherein the time sequence data is a time sequence graph obtained by plotting a plurality of points corresponding to the plurality of examination data in time sequential order.

16. The apparatus according to claim 8 , wherein the time sequence data is related to a fundus layer thickness.

17. The apparatus according to claim 1 , wherein the instructions, when executed by the hardware processor, further cause the plurality of two-dimensional images to be selected in accordance with a user operation to the time sequence data.

18. The apparatus according to claim 14 , wherein the instructions, when executed by the hardware processor, further cause the plurality of two-dimensional images to be selected in accordance with a user operation to the time sequence graph.

19. The apparatus according to claim 8 , wherein the instructions, when executed by the hardware processor, further cause the plurality of two-dimensional images to be selected in accordance with a user operation to the time sequence data.

20. The apparatus according to claim 8 , wherein the plurality of two-dimensional images each represents a fundus layer thickness map or a fundus tomogram.

21. The apparatus according to claim 8 , wherein the instructions, when executed by the hardware processor, further cause the display device to display the obtained plurality of two-dimensional images side in a cross direction of a display screen of the display device.

22. The apparatus according to claim 1 , wherein the plurality of two-dimensional images are selected among two-dimensional images corresponding to the plurality of tomographic images.

23. The apparatus according to claim 1 , wherein the plurality of two-dimensional images displayed side by side in the second display area are changed in accordance with the user instruction.

24. The apparatus according to claim 1 , wherein the instructions, when executed by the hardware processor, further cause the display device to display a selection button for selecting the plurality of two-dimensional images, and further cause the display device to display a selection screen based on the user instruction executed on the selection button displayed by the display device, and
wherein the plurality of two-dimensional images are selected by using the selection screen displayed by the display device.

25. The apparatus according to claim 8 , wherein the plurality of two-dimensional images displayed side by side in the second display area are changed in accordance with a user instruction.

26. The apparatus according to claim 8 , wherein the instructions, when executed by the hardware processor, further cause the display device to display a selection button for selecting the plurality of two-dimensional images, and further cause the display device to display a selection screen based on a user instruction executed on the selection button displayed by the display device,
wherein the plurality of two-dimensional images are selected by using the selection screen displayed by the display device.
