Abstract: Disclosed is an optical coherence tomography (OCT) system according to an exemplary embodiment of the present disclosure.

Abstract: Disclosed is an optical probe of an optical coherence tomography (OCT) system according to an exemplary embodiment of the present disclosure. The optical probe of the OCT system includes: an optical fiber receiving light generated from a light source and transferring the received light to a plurality of lenses and receiving light reflected from tissue from the plurality of lenses and transferring the received light to an optical coherence system; a plurality of lenses including a first lens positioned at a distal end of the optical fiber and a second lens positioned at a predetermined point in a longitudinal direction of the optical fiber; and a sheath capable of accommodating the optical fiber therein.

Abstract: Disclosed is a method of scanning a blood vessel according to several exemplary embodiments of the present disclosure. The method may include: inserting a first catheter for applying a fluorescent material into the blood vessel; applying the fluorescent material to a target point in the blood vessel using the first catheter; inserting a second catheter for scanning the blood vessel into the blood vessel after removing the first catheter from the blood vessel; and acquiring microstructure information and biochemical information of the blood vessel by using the second catheter after the second catheter is inserted into the blood vessel.
