Adaptive Optics for Optical Coherence Tomography
Massachusetts General Hospital
posted on 07/06/2011
Technology: Innovators from the Wellman Center for Photomedicine developed a polarization sensitive optical coherence tomography (PS-OCT) system that incorporated adaptive optics. This adaptive optics approach uses the core and the cladding of a fiber to correct for wave front aberrations rather than use a wave front sensor, like other adaptive optic approaches. When incorporated into the PS-OCT system, the adaptive optics generate an improved image quality and sharpness because it increases the signal-to-noise ration, produces a higher lateral resolution and decreases speckle size. Application: ophthalmic imaging, more specifically diagnosis and management of Glaucoma. Advantages: - Improved image quality and sharpness enables better disease diagnosis and management. - Simple design decreases the complexity and cost of a PS-OCT system.
