Graphical representation of the ADCF algorithm: The maximum diameter of the distorted sphere (D) is measured to determine the ideal sphere shape. The projected diameter of each slice (Di) is determined and assigned a new position (Hc) based on projected diameter a perfect sphere should have. The corrected position (Hc) is then related to the distorted position (Hm) for curve fitting purposes.
