Classification: CPC G | IPC G

Claim 10:
11. The computer system of claim 10, wherein the CT scan based image of the DPF sample is a first CT scan based image generated at a first energy level, and wherein the processing circuit is further structured to:
generate a second CT scan based image of the DPF sample at a second energy level different from the first energy level, the at least one region is common to the first CT scan based image and the second CT scan based image;
determine a mean atomic number for the at least one region;
determine the density of the portion of the DPF sample based on the mean atomic number; and
determine at least one of a contamination level and a contaminant within the portion of the DPF sample by correlating the mean atomic number to a known contaminant.
