Abstract:
1. A combined system which synchronizes optical coherence tomography and acoustic radiation force for simultaneously imaging and mechanically displacing interior body tissue in a patient, which comprises: an endoscopic probe: a piezoelectric transducer located inside the endoscopic probe for delivering acoustic radiation force to a target area of the interior body tissue to mechanically displace the interior body tissue; an optical coherence tomography device having a light source located inside the endoscopic probe to provide infrared light, a movable mirror located inside the endoscopic probe to receive the infrared light from said light source, an actuator device located inside the endoscopic probe to move said movable mirror to direct the infrared light from the light source to scan across the target area to illuminate the interior body tissue before and during delivery of the acoustic radiation force by said piezoelectric transducer, and a lens located inside the endoscopic probe to receive images of the target area of the tissue before and during the delivery of the acoustic radiation force as the infrared light scans across the target area of the interior body tissue, and a controller for determining a displacement of the target area of the interior body tissue resulting from the delivery of the acoustic radiation force.
