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
Background: To determine the basic physical and dosimetric properties of a new synthetic single-crystal diamond detector and its application for relative small field dosimetry. Materials and Methods: The pre-irradiation dose required to stabilize detector response, dose rate dependence, photon and electron energy dependence, temperature dependence and angular dependence of MicroDiamond detector...
متن کاملMeasurements of the relative output factors for CyberKnife collimators.
OBJECTIVE To determine accurately the relative output factors, defined as the ratio of the nominal dose rate for a given collimator to that of the 60-mm collimator. This is particularly important for radiosurgical treatment of functional disorders, such as trigeminal neuralgia, in which a single large radiation dose is delivered to the target with a small collimator, such as the 5-mm collimator...
متن کاملClinical radiation therapy measurements with a new commercial synthetic single crystal diamond detector
A commercial version of a synthetic single crystal diamond detector (SCDD) in a Schottky diode configuration was recently released as the new type 60019 microDiamond detector (PTW-Freiburg, Germany). In this study we investigate the dosimetric properties of this detector to independently confirm that findings from the developing group of the SCDDs still hold true for the commercial version of t...
متن کاملp-CVD diamond heavy-ion beam detector with integrated electronics
For the new ToF Barrel of FOPI, [1], a new beam detector based on polycrystalline-CVD diamond was developed. The new device replaces the existing beam monitoring system which comprise a ToF Start detector and a beam-halo detector, both built from plastic scintillator material. However, since the employed diamonds are not sensitive to minimum ionizing particles the new device can be used efficie...
متن کاملCharacterization of a new commercial single crystal diamond detector for photon- and proton-beam dosimetry
A synthetic single crystal diamond detector (SCDD) is commercially available and is characterized for radiation dosimetry in various radiation beams in this study. The characteristics of the commercial SCDD model 60019 (PTW) with 6- and 15-MV photon beams, and 208-MeV proton beams, were investigated and compared with the pre-characterized detectors: Semiflex (model 31010) and PinPoint (model 31...
