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 method of collecting image data of the eye using an optical coherence tomography (OCT) system, said method comprising:
acquiring a volume of OCT data consisting of multiple B-scans across a transverse area of the eye, wherein one or more B-scans in the volume have a higher resolution than the resolution of the other B-scans in the volume, and wherein the higher resolution B-scans in the volume are collected by reducing the spacing between A-scans in the B-scan as compared to the spacing between A-scans in the lower resolution B-scans of the volume; and
storing or displaying the OCT volume or the higher resolution B-scans.

2. The method as recited in claim 1 , wherein the one or more higher resolution B-scans are located in the central portion of the of volume of OCT data.

3. The method as recited in claim 1 , wherein the one or more higher resolution B-scans are the central horizontal and vertical B-scans of the volume.

4. The method as recited in claim 1 , wherein the B-scans in the volume are displayed to the user in a movie format.

5. The method as recited in claim 4 , wherein the B-scans in the center of the volume are displayed in the movie format at a slower rate than the B-scans on the outer edges of the volume.

6. The method as recited in claim 1 , further comprising taking a maximum intensity projection of a collection of B-scans in the volume and displaying the resulting view to the user.

7. The method as recited in claim 6 , wherein the maximum intensity projection is taken along the y-axis of the volume.

8. The method as recited in claim 6 , wherein the maximum intensity projection is taken along the z-axis of the volume.

9. The method as recited in claim 6 , wherein the maximum intensity projection is taken along the x-axis of the volume.

10. The method as recited in claim 1 , further comprising taking a minimum intensity projection of a collection of B-scans in the volume and displaying the resulting view to the user.

11. The method as recited in claim 10 , wherein the minimum intensity projection is taken along the y-axis of the volume.

12. The method as recited in claim 10 , wherein the minimum intensity projection is taken along the z-axis of the volume.

13. The method as recited in claim 10 , wherein the minimum intensity projection is taken along the x-axis of the volume.
