Claim 9:
10. A computer system structured to determine a density of particulate matter in a diesel particulate filter (DPF) sample, the computer system comprising a processing circuit having a processor and a memory, the processing circuit structured to:
generate a computed tomography (CT) scan-based image of the DPF sample;
segment the CT scan-based image of the DPF sample into a plurality of regions; and
for at least one region from the plurality of regions,
determine a density of a portion of the DPF sample corresponding to the at least one region of the CT scan-based image of the DPF sample by:
determining a grayscale value for the at least one region of the plurality of regions in the particulate filter;
determining a reference value for the at least one region based on a reference sample;
comparing the grayscale value to the reference value, wherein the reference value is correlated to a certain density level; and
determining the density based on the comparison to the reference value which indicates the density level; and
cause an electronic display of a user device communicatively coupled to the computer system to display the CT scan-based image comprising the at least one region and an indication of the density for the at least one region.
