The principal aim of radiotherapy is to deliver a dose of ionising radiation to the target volume, with simultaneous minimization of radiation absorbed by healthy tissues. The radiation beam modelling is an important method of minimisation of the dose absorbed by healthy tissues and critical structures. The therapeutic field is usually rectangular or square. Its shape depends on position of the collimator jaws in the therapeutic apparatus. However, a target volume may have various shapes. Therefore, some additional devices are necessary to shape the therapeutic field appropriately to the shape of the irradiated area. A multileaf collimator (MLC) is a device allowing shaping of irregular fields and reproduction of any shape of the irradiated volume. It is a set of mobile leafs able to block some selected fractions of the radiation beam. When access to the tumour volume is limited by neighbouring organs at risk, MLC width may significantly influence distribution of dose in the tumour and protection of neighbouring critical organs.
