Abstract :
Computation of a three-dimensional dose distribution in an irradiated region of a patient is a challenging problem. A parallel architecture based on a recruit-on-demand (ROD) strategy is proposed to solve this problem in a reasonable time. In this architecture, an expert analyzer assesses the total requirements of a plan. The expert analyzer then assigns jobs to available processors in such a fashion that the computational load is distributed equally among processors. The processors compute the dose in parallel and deliver final results to the users
