Claim 13:
14. A method of determining concentricity of a golf ball, the method comprising:
via an imager,
capturing a first x-ray image of a golf ball at a first orientation at a base energy level emitted via at least one x-ray source;
capturing a second x-ray image of the golf ball at the first orientation at a reduced energy level emitted via the at least one x-ray source;
capturing a third x-ray image of the golf ball at a second orientation at the base energy level emitted via the at least one x-ray source, wherein the second orientation is angularly offset relative to the first orientation;
capturing a fourth x-ray image of the golf ball at the second orientation at the reduced energy level emitted via the at least one x-ray source; and

via a processor, determining an overall eccentricity of the golf ball based on a first eccentricity of the golf ball at the first orientation and a second eccentricity of the golf ball at the second orientation.
