Abstract
A combined system and method synchronizes optical coherence tomography and acoustic radiation force for simultaneously imaging and mechanically displacing tissue in a patient as a detection and analytic tool. An endoscope is provided which has a piezoelectric element and an OCT scanner. The piezoelectric element generates the acoustic force to displace the tissue. The OCT scanner images the tissue and the system determines the mechanical displacement of the tissue. Cancer and arterial plaques can be recognized from the mechanical displacement of the tissue.
