1. A method for enhancing multi-dimensional image data, the image data comprises a series of multi-dimensional images to be displayed at a frame rate, the method comprising: (a) for each image in the series, scanning the image in a plurality of dimensions; and (b) first, performing in a single pass the following steps for a first dimension of the plurality: applying a low pass filter to the data contained in the first dimension and decimating the data contained in the first dimension, wherein the low pass filter is substantial such that much of the high-frequency data contained in the first dimension is suppressed; (c) second, performing in a single pass the following steps for a second dimension of the plurality; applying a low pass filter to the data contained in the second dimension and decimating the data contained in the second dimension, wherein the low pass filter is substantial such that much of the high-frequency data contained in the second dimension is suppressed; (d) for each of the plurality of dimensions, interpolating the decimated data to a pixel density that matches the pixel density of the image: and (e) performing steps (a) through (d) at least as fast as the frame rate.
