Excerpt

Purpose: To select quality coplanar solutions to the beam orientation optimization (BOO) problem in intensity‐modulated radiation therapy (IMRT) treatment planning, and to demonstrate that high‐quality treatment plans can be obtained using fewer beams than typically used in equi‐spaced plans. Method and Materials: We consider the problem of obtaining quality 3‐and 4‐beam coplanar radiation treatment plans. Two methods to obtaining these solutions are tested: the simulated annealing (SA) algorithm, which provides …
