1. A method for visualizing temporal phenomena and constructing 3D views from a series of medical images, said method comprising the steps of: providing a first time series of digital images of contrast-enhanced blood flow in a patient, each acquired from a same viewing point with a known epipolar geometry, each said image comprising a plurality of intensities associated with an N-dimensional grid of points; calculating one or more time-density curves from said first time series of digital images, each curve indicative of how the intensity at corresponding points in successive images changes over time; and generating one or more overview images from said time density curves using a color coding technique, wherein each of said one or more overview images depict how a physical property value changes from said blood flow at selected corresponding points in said first time series of images.
