Michelson Diagnostics Ltd. of Orpington, UK, has signed an exclusive worldwide license with University Health Network of Toronto to obtain a patent that covers the use of multiple optical beams to extend the depth of focus and to improve imaging performance in optical coherence tomography. The technology overcomes the problem of limited transverse optical resolution that is associated with Fourier-domain optical coherence tomography imaging. Teams from both organizations are collaborating to demonstrate the technology using in vivo flexible probes in animal imaging, working toward implementation in humans undergoing gastrointestinal endoscopy.
