<p>A system for identifying vulnerable plaque includes a catheter (16) having a collection fiber (20) and a delivery fiber (18) therethrough. The catheter (16) is engaged to a distal face (46) of a housing (42) configured to spin about an axis. The proximal face (44) of the housing (42) has a central aperture (56). First (64) and second (70) optical relays extend respectively between the central aperture (56) and a central port (52) on the distal face (46) and between a detector (66) and an eccentric port (54) on the distal face. The central (52) and (eccentric54) ports are in optical communication with the delivery (18) and (20) collection fibers respectively.</p> |
