    Medical Imaging - FPGA-based processing transforms high-speed OCT
    n medical image-processing systems such as those used for retinal imaging, 3-D images need to be generated at high speeds. One of the most common techniques is optical coherence tomography (OCT), an optical signal-processing method that uses relatively long-wavelength light (on the order of 800 nm) to penetrate the object to be examined. In OCT systems, this light is first optically split into two paths: a sample path used to illuminate the object and reference path. Light reflected from the object is combined with the reference beam, resulting in an interference pattern. This interference pattern contains information that can be ...
