Quantification of head leakage radiation in CyberKnife robotic radiosurgery systems using a multimodal approach.

ABSTRACT: This study aims to measure the head leakage radiation of a CyberKnife system (Model-S7 (without MLC)) in-patient and out-of-patient planes using optically stimulated luminescence dosimeters (OSLDs), vented ionization chambers, and a pressurized ionization chamber-based survey meter, and to compare the measured leakage levels with the limits specified by the International Electrotechnical Commission (IEC) standards. In this study, a CyberKnife LINAC equipped with a 6 MV flattening filter-free (FFF) beam and a maximum circular field size of 6 cm in diameter was utilized. Leakage radiation was assessed for both IRIS and FIXED collimators in their fully closed positions. Three independent measurement techniques were employed to quantify leakage: optically stimulated luminescence dosimeters (OS
