1. A method for viewing a biological or medical image of tissue or an organ wherein the tissue or organ has been treated with a contrast agent comprising: a) providing an at least 2-dimensional high bit level digital image of the biological or medical image; b) subjecting the medical image to magnitude enhancement analysis such that at least one relative magnitude across at least a substantial portion of the image is depicted in an additional dimension relative to the at least 2-dimensions to provide a magnitude enhanced image such that additional levels of magnitudes are substantially more cognizable to a human eye compared to the 2-dimensional image without the magnitude enhancement analysis; c) displaying a selected portion of the enhanced medical image on a display comprising a display system wherein the display system has a bit level display capability less than the bit level of the digital medical image; and d) providing a moveable window configured to display a selected portion of the medical image such that the window can move the selected portion among an overall range of the bit level information in the high bit level image.
