Patent ID: 8287126

Claim:
A method of visualizing objects using an optical system including an OCT system configured to obtain OCT data from voxels within a first volume having a first lateral extent, the method comprising: obtaining position data indicative of a position of a predetermined portion of a movable instrument relative to the optical system; determining a first set of voxels from the voxels of the first volume based on the determined position such that at least 80% of the first set of voxels is located within a second volume, the second volume having a second lateral extent, wherein the second lateral extent has a size which is at least 2 times smaller than a size of the first lateral extent; obtaining OCT data of the first set of voxels; visualizing a representation of the OCT data of the first set of voxels; and repeating the obtaining of the position data, the determining of the first set of voxels, the obtaining of the OCT data of the first set of voxels and the visualizing of the representation at a first repetition rate higher than 5 times per second.
