1. A method for determining porosity of a part comprising:
determining scan data of the part, the scan data comprising data of a plurality of sequential segments, wherein determining scan data of the part comprises determining scan data within a region of interest based on the scan data of the plurality of sequential segments;
determining a background model for the part, the scan data, or both, wherein determining the background model for the part, the scan data, or both comprises determining background data within the region of interest based on the background model; and
determining a bulk porosity based on a difference between the scan data and the background model, wherein determining the bulk porosity based on the difference between the scan data and the background model comprises determining data indicative of a signal to background ratio within the region of interest relating the scan data to the background data.
