Abstract

The present invention is an OCT imaging system user interface for efficiently providing relevant image displays to the user. These displays are used during image acquisition to align patients and verify acquisition image quality. During image analysis, these displays indicate positional relationships between displayed data images, automatically display suspicious analysis, automatically display diagnostic data, simultaneously display similar data from multiple visits, improve access to archived data, and provide other improvements for efficient data presentation of relevant information.

First claim

We claim:

1. A graphical user interface for use with a system having an optical coherence tomography (OCT) module and a fundus imaging module both of which are aligned with a patient's eye, and a host CPU, said interface comprising:
a display for presenting a fundus image of the eye, and an image generated from OCT measurement data;
wherein said image generated from OCT measurement data is overlaid on said fundus image and wherein at least one of said image generated from OCT measurement data and said fundus image is a live image.

2. The interface of claim 1 , wherein the fundus image and the image generated from OCT measurement data are registered to each other.

3. The interface of claim 2 , wherein the fundus image and the image generated from OCT measurement data were not generated during the same exam.

4. The interface of claim 3 , wherein an observed level of registration between the fundus image and the image generated from OCT measurement data is used to facilitate an alignment for a current exam.

5. The interface of claim 4 , wherein the alignment is performed manually by a user.

6. The interface of claim 4 , wherein the alignment is performed automatically by the host CPU.

7. The interface of claim 6 , wherein the performing of the alignment by the host CPU includes adjusting one or more scanning mirrors.

8. The interface of claim 6 , wherein the system further includes a fixation target subsystem, and the performing of the alignment by the host CPU includes moving the fixation target, whereby the patient changes the position of the patient's eye.

9. The interface of claim 1 , wherein the image generated from OCT measurement data is an en-face image.

10. The interface of claim 9 , wherein blood vessels in the fundus image are rendered on the display with a first color and blood vessels in the en-face image are rendered on the display with a second color different than the first color.

11. The interface of claim 1 , where a partial en-face image is displayed in real time during acquisition of the OCT measurement data to determine if alignment of the OCT module is correct prior to the completion of the full data acquisition for the en-face image.

12. The interface of claim 1 , wherein the image generated from OCT measurement data is a thickness map.

13. The interface of claim 1 , wherein the fundus image is derived from information obtained on a previous patient visit and is used to reposition the patient in the same position as in the previous visit.

14. The interface of claim 1 , wherein a level of transparency of the overlay is variable.

15. The interface of claim 14 , wherein the level of transparency of a region of the overlay is selected based on a level of pathology associated with that region of the overlay.

16. A graphical user interface for use with a system having an optical coherence tomography (OCT) module and a fundus imaging module both of which are aligned with a patient's eye, and a host CPU, said interface comprising:
a display for presenting a fundus image of the eye, and an image generated from OCT measurement data;
wherein said image generated from OCT measurement data is overlaid on and registered to said fundus image and wherein the fundus image and the image generated from OCT measurement data were not generated during the same exam and wherein the level of registration between the fundus image and the image generated from OCT measurement data is used to facilitate an alignment for a current exam wherein the alignment is performed automatically by the host CPU by adjusting one or more scanning mirrors.

17. A graphical user interface for use with a system having an optical coherence tomography (OCT) module and a fundus imaging module both of which are aligned with a patient's eye, and a host CPU, said interface comprising:
a display for presenting a fundus image of the eye, and an image generated from OCT measurement data;
wherein said image generated from OCT measurement data is overlaid on said fundus image and wherein a partial en-face image is displayed in real time during acquisition of the OCT measurement data to determine if alignment of the OCT module is correct prior to the completion of the full data acquisition for the en-face image.

18. A graphical user interface for use with a system having an optical coherence tomography (OCT) module and a fundus imaging module both of which are aligned with a patient's eye, and a host CPU, said interface comprising:
a display for presenting a fundus image of the eye, and an image generated from OCT measurement data;
wherein said image generated from OCT measurement data is overlaid on said fundus image and wherein the image generated from OCT measurement data is a thickness map.

19. A graphical user interface for use with a system having an optical coherence tomography (OCT) module and a fundus imaging module both of which are aligned with a patient's eye, and a host CPU, said interface comprising:
a display for presenting a fundus image of the eye, and an image generated from OCT measurement data;
wherein said image generated from OCT measurement data is overlaid on said fundus image and wherein the fundus image is derived from information obtained on a previous patient visit and is used to reposition the patient in the same position as in the previous visit wherein the fundus image.

20. A graphical user interface for use with a system having an optical coherence tomography (OCT) module and a fundus imaging module both of which are aligned with a patient's eye, and a host CPU, said interface comprising:
a display for presenting a fundus image of the eye, and an image generated from OCT measurement data;
wherein said image generated from OCT measurement data is overlaid on said fundus image wherein a level of transparency of the overlay is variable.
