摘要: We present an algorithm for optimal step-and-shoot multileaf collimator field segmentation minimizing tongue-and-groove effects. Adapting the concepts of [7] we characterize minimal decomposition time as maximal weight a path in properly constructed weighted digraph. also show that this can be realized by unidirectional plan, thus proving from [9] is monitor unit general and not only leaf movement. Our characterization has advantage it used to derive heuristic reduction number shape matrices following ideas [7].
