1. A system comprising:
a processing platform comprising one or more processing devices operatively coupled to one or more memory devices;
the processing platform being configured to:
acquire a plurality of sets of optical coherence tomography (OCT) image data for a target object volume;
reconstruct space-domain OCT images for each of the plurality of sets of OCT image data;
generate coherent-averaged OCT image data having at least two dimensions by coherently averaging the space-domain OCT images to suppress noise or enhance a signal-to-noise ratio; and
computationally expand a spatial-frequency bandwidth of the coherent-averaged OCT image data, at higher frequencies, via a magnitude-based deconvolution using a multi-dimensional bandwidth expansion mask.
