Abstract
A spectroscope for detecting vulnerable plaques includes an optical fiber extending through a catheter. The optical fiber has a field-of-view that is modified to preferentially collect light scattered from deep within the wall of a blood vessel. Obstructions or curved optical surfaces can be used to modify the field of view.
