1. A method of inspecting a plurality of objects using a computed tomography (CT) system, the method comprising:
acquiring an image of a fixture used for holding the plurality of objects with the CT system;
generating a first electronic model of the fixture;
placing the plurality of objects in the fixture;
acquiring an image of the fixture and the plurality of objects with the CT system;
generating a second electronic model of the fixture and the plurality of objects;
defining a third electronic model of the plurality objects based at least in part on subtracting the first electronic model from the second electronic model;
comparing dimensions of the objects from the third electronic model with a computer aided design (CAD) model; and
outputting a report based at least in part on the comparison of the objects from the third electronic model with the CAD model.
