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

      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 ...

    2. Balloon system including registration marking

      Balloon system including registration marking

      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 ...
