During the delivery of intensity-modulated radiation therapy (IMRT) by the multileaf collimator (MLC) step-and-shoot technique, it is required to sequence the two-dimensional intensity-modulated beams (2D IMBs) into a series of components that can be shaped with the MLC. In this paper it is shown that the use of an MLC that has four banks of leaves (in two orthogonal pairs) instead of two banks only is advantageous for this purpose.
在多叶准直器（MLC）步进式强度调制放射治疗（IMRT）的实施过程中，需要将二维强度调制射束（2D IMB）序列化为一系列可由 MLC 形成的组件。本文表明，为此目的使用具有四组叶片（两对正交）的 MLC 比仅使用两组叶片更为有利。
