20140355856 | RECONSTRUCTION OF OPTICAL COHERENT TOMOGRAPHY (OCT) IMAGES OF MORPHOLOGICAL FEATURES - Imaging devices and processing techniques based on imaging information along the depth direction in an optical coherent tomography (OCT) image are disclosed to enhance observed morphological features. The methods and systems obtain different OCT images of the target object under different reference path lengths, process the different OCT images to obtain a derivative with respect to the signal path length of image information of the different images, and processing the derivative to extract improved image information of the target object. The derivatives may be in a form related to a gradient value of the normalized OCT image intensity, or an attenuation coefficient. | 12-04-2014 |
