In this work the response of a commercially available diode dosimetry system was studied for two energy qualities, 6MV and 15 MV. Diodes were calibrated against ionization chambers. Signal stability post-irradiation, intrinsic precision, linearity of response with dose and dose decrease under the diode were studied. For each beam energy the response of the diode relative to the given dose as measured by an ionization chamber was evaluated. Diode was calibrated for every energy to give entrance dose, exit dose and eventually the midline dose. Entrance and exit correction factors for field size, tray, source to skin distance, angle and wedge were determined. It was found that diode response i.e. diode reading per cGy of given dose varies significantly with treatment beam set-up. Finally the effects of dose rate, temperature and accumulated dose on the diode’s response were studied. 2009-02-17T09:00:39Z 2009-02-17T09:00:39Z 2005 2009-02-17T09:00:39Z Thesis http://nemertes.lis.upatras.gr/jspui/handle/10889/1382 gr Η ΒΥΠ διαθέτει αντίτυπο της διατριβής σε έντυπη μορφή στο βιβλιοστάσιο διδακτορικών διατριβών που βρίσκεται στο ισόγειο του κτιρίου της. 0 application/pdf |
