    Estimation of weighted multi-scatterer contributions for improvement of lateral resolution of optical coherence tomography images

    A method for improvement of lateral resolution in Optical Coherence Tomography (OCT) is presented. The resolution improvement achieved with this method does not depend on the delivery optics. Moreover the depth of focus is not restricted. The method is based on the lateral oversampling of the image. The laterally oversampled signals are backscattered signals from shifted and overlapped resolution volumes. Signals from successive volumes are correlated due to the region shared by adjacent resolution volumes. By utilizing the cross correlation of signals from such overlapped volumes, resolution can be improved by various degrees depending on which pairs of signals are ...
