Claim 0:
1. A method for determining concentricity of a multiple layer golf ball, the method comprising:
positioning a golf ball for non-rotation in a x-ray measurement region of an imaging machine;
taking at least one X, Z image of a full cross-sectional view of the golf ball using a first x-ray source, a first camera and a first image intensifier;
taking at least one Y, Z image a full cross-sectional view of the golf ball using a second x-ray source, a second camera and a second image intensifier;
determining a diameter or ellipse dimensions of an inner edge and an outer edge of a layer of the multiple layer golf ball utilizing an edge detection algorithm;
calculating X,Z coordinates of a best fit diameter or ellipse of the inner and outer edges of the multiple layer golf ball;
calculating Y, Z coordinates of a best fit diameter or ellipse of the inner edge and outer edge layer of the multiple layer golf ball;
combining the at least one X, Z image and the at least one Y, Z image to calculate a 3 D distance; and
comparing the Y, Z center coordinates and X, Z center coordinates of a specified layer to determine concentricity of an inner layer within any of the outer layers.
