    Optical Coherence Tomography: Bio and beyond - OCT advance breaks barriers in imaging scale, cost

    A research team representing commerce and academia has made a welcome breakthrough in optical coherence tomography (OCT): meter-scale OCT. 1 (For more on OCT, see "Advances in functional OCT," page 66.) Not only does the achievement provide dramatically greater capability than before, it also portends high-performance, low-cost systems, with wide-ranging impact for industrial applications as well as biomedical. It's no surprise that OCT has achieved its greatest success in ophthalmology , and shown the most promise for other uses (such as gastroenterology, cardiology, and dermatology) that benefit from endoscopy-enabled or superficial imaging, as it produces volume images with micron-scale resolution ...
