Claim Text:
1. An article comprising a tangible, non-transitory machine-readable medium that stores a program, the program being executed by a machine having a hardware component to perform a method, the method comprising: receiving a volume dataset defining a volume within a human body; and rendering, with respect to any position and orientation in the volume, an image sequence of the volume dataset at a given number of frames per second, each frame of the image sequence having pixels that are uniform, at least two frames of the image sequence having varying resolution, the image sequence representing a lumen, an open area of an artery, and pixels in a cross-section of the lumen; wherein a given pixel in a frame has a value that is defined as a maximally intense traversed pixel along a ray, as calculated at each step along the ray, from a sum of an absolute value of differences between a sampled pixel and its neighboring pixels in the cross-section of the lumen; wherein neighboring pixels that are part of the lumen and within the cross-section are rendered with a first value, and neighboring pixels that are part of a wall of the artery are rendered in a second value dissimilar to the first value such that the wall of the artery is visually distinguishable from the lumen.
