Duke University, Case Western Reserve University, Jenkins Wilson Taylor & Hunt P A, July 11, 2006: US07075658 (142 worldwide citation)

Spatial information, such as concentration and displacement, about a specific molecular contrast agent, may be determined by stimulating a sample containing the agent, thereby altering an optical property of the agent. A plurality of optical coherence tomography (OCT) images may be acquired, at leas ...
