Determination of small field synthetic single-crystal diamond detector correction factors for CyberKnife, Leksell Gamma Knife Perfexion and linear accelerator
Original language description
Purpose: The aim of this study was to determine small field correction factors for a synthetic single-crystal diamond detector (PTW microDiamond) for routine use in clinical dosimetric measurements. Materials and methods: Correction factors following small field Alfonso formalism were calculated by comparison of PTW microDiamond measured ratio MQclin/M fclin Qmsr fmsr with Monte Carlo (MC) based field output factors ΩQclin Qmsr fclin fmsr , , determined using Dosimetry Diode E or with MC simulation itself. Diode measurements were used for the CyberKnife and Varian Clinac 2100C/D linear accelerator. PTW microDiamond correction factors for Leksell Gamma Knife (LGK) were derived using MC simulated reference values from the manufacturer. Results: PTW microDiamond correction factors for CyberKnife field sizes 25–5mm were mostly smaller than 1% (except for 2.9% for 5mm Iris field and 1.4% for 7.5mm fixed cone field). The correction of 0.1% and 2.0% for 8mm and 4mm collimators, respectively, needed to be applied to PTW microDiamond measurements for LGK Perfexion. Finally, PTW microDiamond MQclin/M fclin Qmsr fmsr for the linear accelerator varied from MC corrected Dosimetry Diode data by less than 0.5% (except for 1×1 cm2 field size with 1.3% deviation). Conclusions: Regarding low resulting correction factor values, the PTW microDiamond detector may be considered an almost ideal tool for relative small field dosimetry in a large variety of stereotactic and radiosurgery treatment devices.
