Abstract
A system for optical coherence tomography includes a source of optical radiation, an optical fiber, and a graded index fiber attached to a distal end of the optical fiber. The optical fiber and the graded index fiber are together configured to provide a common path for optical radiation reflected from a reference interface at a distal end of the graded index fiber and from a target.

(canceled)
A system for optical coherence tomography, comprising:
- a source of optical radiation;
- an elongate catheter body having a side-opening window therein;
- an optical fiber extending within the elongate catheter body;
- an interface medium at a distal end of the optical fiber, the optical fiber having a core providing a common path for optical radiation reflected from the interface medium and a target;
- a lens in optical contact with the interface medium, the lens configured to focus optical radiation through the side-opening window to a focal point in the target, wherein a beam diameter at the focal point is between 10 and 60 microns;
- receiving electronics configured to receive the optical radiation reflected from the interface medium and the target;
- and
- a processor to generate an image of the target based upon the optical radiation received by the receiving electronics.
