A method of qualifying physical components using computed tomography (CT) includes obtaining qualified CT data from a CT scanner for at least one qualified physical component. Qualification data is generated based on the qualified CT data, where the qualification data defines a qualification envelope. Candidate CT data is obtained from the CT scanner for a candidate physical component. Comparison data is then generated based on the candidate CT data and the qualification data, where the comparison data indicates whether the candidate CT data is within the qualification envelope defined by the qualification data. An acceptance signal is generated if the comparison data meets acceptance criteria 1. A method of qualifying physical components using computed tomography (CT) , the method comprising the steps of:obtaining, via the processor, candidate CT data from the CT scanner for a candidate physical component;generating, via the processor, comparison data based on the candidate CT data and qualification data, where the qualification data defines a qualification envelope and where the comparison data indicates whether the candidate CT data is within the qualification envelope defined by the qualification data; andgenerating, via the processor, an acceptance signal if the comparison data meets acceptance criteria.2. The method of claim 1 , where the acceptance criteria requires that the entirety of the candidate CT data is within the qualification envelope defined by the qualification data.3. The method of claim 1 , where:the qualification data comprises a plurality of volumetric pixels (voxels);candidate CT data comprises a plurality of voxels; andthe comparison data comprises a plurality of voxels.4. The method of claim 3 , where each voxel comprises a three-dimensional (3D) location and material information.5. The method of claim 4 , where the material information comprises density information.6. The method of claim 5 , where a feature of the CT scanner comprises ...
