In 2010, U.S FDA approved coronary<unk> <unk><unk>  (OCT) as a new catheter based intra-vascular imaging modality with a resolution higher than intravascular ultrasound (IVUS). OCT uses near infra-red light and constructs images from the reflected light which is in the same phase (i.e cohorent) with the emitted light. This eliminated the interference from scattered light, thereby producing images with higher resolution.
