Abstract

See full text

A method for detecting a target flaw using a radiographic inspection system includes selecting a plurality of simulated flaws. The method also includes performing a flaw detection simulation on the simulated flaws. The method also includes determining a plurality of output indication parameters for each of the simulated flaws based at least partially upon the flaw detection simulation. The output indication parameters include a contrast-to-noise ratio (CNR), a resolution ratio, a length-to-width (L/W) indication ratio, and a probability parameter. The method also includes determining a contrast-to-noise ratio sensitivity function (CNR SF) based at least partially upon the output indication parameters. The method also includes qualifying the radiographic inspection system to detect the target flaw based at least partially upon the CNR SF.
