The present disclosure provides an OCT imaging system to reduce or eliminate frequency-domain aliasing artifacts. The frequency is shifted using a carrier frequency to define a sampling range substantially centered on the carrier frequency. An image of the sample is generated from a displayed imaging range that consists of a subset of the frequencies within the sampling range. Furthermore, the system may be configured to determine the carrier frequency such that a Nyquist frequency corresponding to the shifted frequency is extended beyond either an upper or a lower bound of an OCT quality envelope corresponding to the first portion of light. Additionally, the carrier frequency may be determined such that a lower bound of the OCT quality envelope is greater or less than a zero-frequency DC limit.

Frequency-domain optical coherence tomography with extended field-of-view and reduction of aliasing artifacts

A system for registering images is provided. The system includes a first imaging device having an imager positioned at a distal end thereof. The first image device is configured to produce a first image of a body cavity. The system includes an imaging system having a second imaging device having an imager positioned at a distal end thereof and configured to be positioned approximate to said imager of said first imaging device within said body cavity and configured to produce a second image. An elongated member having an outer surface is molded to include imaging markers such that said imaging markers are embedded within the outer surface. At least one of the image markers is configured to produce registration information in the first image and the second image.
