Beam selection for stereotactic ablative radiotherapy using Cyberknife with multileaf collimation

The Cyberknife system (Accuray Inc., Sunnyvale, CA) includes a multileaf collimator (MLC), which allows maximal flexibility in field shaping and fewer monitor units in stereotactic radiosurgery than with a cone collimator [1,2]. The MLC consists of 26  leaf pairs, each of width 3.85 mm, giving a maximum field size of 115 mm × 100 mm at a nominal source-axis distance of 800 mm.
