Název v původním jazyce

Assessment of basic physical and dosimetric parameters of synthetic single-crystal diamond detector and its use in Leksell Gamma Knife and CyberKnife small radiosurgical fields

Popis výsledku v původním jazyce

Background: To determine the basic physical and dosimetric properes of a new synthec single-crystal diamond detector and its applicaon for relave small field dosimetry. Materials and Methods: The pre-irradiaon dose required to stabilize detector response, dose rate dependence, photon and electron energy dependence, temperature dependence and angular dependence of MicroDiamond detector response were evaluated. Output factors on Leksell Gamma Knife Perfexion and on CyberKnife were measured to assess detector feasibility in small radiaon field dosimetry. For all measurements, the detector was connected to Unidos electrometer set to 0 voltage. Results: Relave output factors measured on Leksell Gamma Knife Perfexion for 4 mm and 8 mm collimators were in agreement with Monte Carlo reference values from the manufacturer, with deviaons of 0.3% and 2.1%, respecvely. For CyberKnife and fixed circular collimators, the difference in output factor values did not exceed 2% from vendor-supplied values, even for the smallest radiaon field with a diameter of 5 mm. Conclusion: Our results indicate that the MicroDiamond detector is a promising tool for relave small field dosimetry. For output factor measurements on Leksell Gamma Knife Perfexion and CyberKnife, the detector can be used with minimal response correcons applied (correcon factors not larger than 2%).
