Abstract
A system and method for detecting tumors. Three-dimensional scans of a patient are performed with penetrating radiation, before and/or after the injection of a contrast agent. Raw density arrays are formed from the scans. The median density within an organ is calculated and subtracted from each of the raw density arrays, to form offset arrays. The offset arrays are subtracted pairwise and the differences are summed to form a discriminator array.
