Abstract
A non-linear guidance method for radiation detection is described herein wherein a heuristic non-linear radiation detection method is utilized is for the location of sentinel nodes for staging cancer. The method of radiation detection described herein includes the steps of: Generating radiation decay rate counts wherein the counts are a sum of detected radiation decay events over a time interval; loading the counts into an array; summing selected elements of the array to generate a total count and a plurality of candidate counts; comparing the total count to one of the candidate counts to determine whether the one of the candidate counts is statistically different from the total count; using the statistically different one of the candidate counts as an output count rate; and generating an output signal using the output count rate to determine the characteristics of the output signal.
