To determine the potentialities of synthetic single crystal diamond Schottky diodes for accurate dose measurements in radiation therapy small photon beams.The dosimetric properties a diamond-based detector were assessed by comparison with reference microionization chamber. The device was operated at zero bias voltage under irradiation high-energy radiotherapic beams. stability response and its rate dependence measured. Different square field sizes ranging from 1 × cm(2) to 10 used during...
The correction for charge recombination was determined different plane-parallel ionization chambers exposed to clinical electron beams with low and high dose per pulse, respectively. energy nearly the same (about 7 9 MeV) any of used. Boag's two-voltage analysis (TVA) used determine ion losses, k(s), relevant each chamber considered. presence free electrons in air cavity accounted determining k(s) by TVA. determination made on basis models proposed past years Boag, Hochhäuser Balk account...
A chemical vapour deposition diamond detector fabricated at Rome 'Tor Vergata' University was investigated for its applicability as transfer dosimeter in radiotherapy photon beams with small field sizes. The consists of a single crystal very sensitive volume (0.004 mm3). showed measurement repeatability 0.1% and long term reproducibility 0.4%. Monte Carlo simulations revealed response dependence on the beam energy about 2% from 60Co quality to 10 MV beam. calculated found be independent size...
LIAC® and NOVAC are two mobile linear accelerators dedicated to intraoperative radiation therapy (IORT), generating electron beams in the energy range of 3-12 MeV. Due high dose-per-pulse (up 70 mGy per pulse), 2003 Italian National Institute Health (ISS) stated that "for measure dose water reference conditions, ionization chambers cannot be employed no published dosimetry protocol can used". As a consequence, ferrous sulphate (or, alternatively alanine) was recommended. Based on...
