A new method of rapid simulation including design, verification and patient marking for shaped fields is described. This system utilizes a 'pseudoblock' constructed from the Styrofoam components of the Cerrobend blocking system. The procedure is precise; errors in block aperture or patient positioning can readily be seen and corrected before the block is cast. In addition, the use of the pseudoblock does not significantly increase the time the patient spends in the simulator on his initial visit.
