1. A method for determining concentricity of a multiple layer golf ball, the method comprising:
averaging a first plurality of images of the full cross-sectional view of the golf ball using a x-ray source and a digital detector into a single first image of a full cross-sectional view of the golf ball;
calculating Y,Z center coordinates of a best fit diameter or ellipse of an inner edge layer and an outer edge layer of a specific layer of the multiple layer golf ball using the single first image of the full cross-sectional view of the golf ball;
averaging a second plurality of images of the full cross-sectional view of the golf ball in the new orientation using the x-ray source and the digital detector into a second single image of the full cross-sectional view of the golf ball;
calculating X,Z center coordinates of a best fit diameter or ellipse of the inner edge layer and outer edge layer of the specific layer of the multiple layer golf ball; and
comparing the X,Z and Y,Z center coordinates of the specific layer to determine the concentricity of the specific layer within an outer layer of the multiple layer golf ball.
