Experience with a double dose-monitoring system in the 18 MeV betatron therapy
Description
Correct setting of the patient dose within a range of about +- 3% is only achieved if a second exposure monitoring system controls the output variations of a betatron beam. A sealed thimble chamber attached in the centre of the field on the patient, which switches off the betatron when a given exposure has exceeded proved as a safe device. (orig.)
Abstract (German)
Zur Einhaltung einer vorgewaehlten Patientendosis innerhalb +- 3% fuer die 18 MeV Betatrontherapie hat sich eine zweite, im Zentrum des Bestrahlungsfeldes auf dem Patienten angebrachte Ionisationskammer bewaehrt. Diese Kammer schaltet bei Ueberschreiten des Sollwertes um 15% und bei Ausfall des eingebauten Monitorsystems das Betatron ab. Damit ist eine groessere Sicherheit gewaehrleistet.
