Optical coherence tomography cross view imaging

1. An optical coherence tomography (OCT) system comprising:

a processor coupled to a non-transitory computer readable medium; and

computer-executable instructions carried on the non-transitory computer readable medium, the instructions readable by the processor are executed to cause the processor to:

acquire a first B-scan image and a second B-scan image;

perform a perspective transformation on each B-scan image;

couple the first B-scan post-transformation image to the second B-scan post-transformation image at an angle of between 30 degrees and 170 degrees to generate a cross view image; and

display the cross view image by displaying the first B-scan post-transformation image and the second B-scan post-transformation image as two B-scan cross-section views of a three dimensional volume, wherein the first b-scan post-transformation image displayed is arranged at an angle of between 30 degrees and 170 degrees with respect to the second b-scan post-transformation image displayed, and the first b-scan post-transformation image is displayed simultaneously with the second b-scan post-transformation image.

13. The OCT system of claim 12 , wherein the cross view image is presented on the display with no more than a 120 millisecond delay from when the first B-scan is acquired.

14. The OCT system of claim 12 , wherein the cross view image is presented on the display with no more than a 1 second delay from when the first B-scan is acquired.

15. The system of claim 1 wherein an affine transformation is used to perform a perspective transformation on each B-scan image.

16. A method for cross view imaging using an optical coherence tomography system (OCT), the method comprising:

acquiring a first B-scan image and a second B-scan image;
