Abstract:
A method for constructing a two dimensional image from a three dimensional array of angiographic data, comprising:a) obtaining the three dimensional array of angiographic data, wherein the array of angiographic data contains a plurality of data points; b) constructing a plurality of rays through the array of angiographic data; c) for each of the plurality of rays, selecting n data points intersected by the ray in the array of angiographic data, wherein n is greater than one, but less than the total number of data points intersected by the ray and the n data points selected for a given ray have intensities at least as great as the other data points intersected by the ray; and d) constructing the two dimensional image based upon a summation of the n data points selected for each of the plurality of rays.
