1. A method of automatically optimizing medical three-dimensional visualizations comprising: isolating a plurality of anatomical structures within the medical three-dimensional visualization; calculating the number of ray intersects, that intersect more than one of said plurality of anatomical structures, for a plurality of casting angles; selecting an optimum casting angle that minimizes said ray intersects from one of said plurality casting angles; and displaying the optimized medical three-dimensional visualization from said optimized casting angle.
