Abstract
AimThis study assesses the implementation of MOSkin detectors for the SRS dosimetry of the CyberKnife® system. MethodThe performance of the MOSkin detectors was evaluated by using Iris collimators on water-equivalent phantoms in the CyberKnife® system. The dosimetric evaluation included measurements of the tissue–phantom ratio (TPR), output factor, and off-axis ratio. The results of the MOSkin sensors were compared with those of PTW 60016 and EDGE diodes. ResultsThe TPR measurements obtained by the MOSkin devices exhibited conformity lower than 2.9% compared with the results of the PTW60016 diodes across the field sizes considered. The output factor was consistent to within 2.8% of that of the EDGE detectors, following adjustment based on the appropriate field correction factors. The off-axis ratio of the MOSkin detectors corresponded to that of the EDGE diodes, with an FWHM of 4.3% and a penumbra narrower than 0.22 mm. ConclusionMOSkin sensors are strong contenders for Cyberknife® quality assurance of both machines and patients, as they are capable of reproducing measurements obtained by commercial sensors with an acceptable degree of precision.
