1. A system for visualizing relatively small structures within an object, said system comprising: an image acquisition sub-system for acquiring a dataset for a volume of interest; and a processor for generating image data from the acquired data, said processor programmed to execute a high resolution filter kernel algorithm comprising a weighting factor applied to a ramp filter that scales relatively high frequency regions of the image dataset by a factor greater than one, and a windowing function applied to the weighted ramp filter that facilitates reducing aliasing artifacts in reconstructed images generated from the image dataset.
