1. 1. Calibration of Ionization Chambers for Measuring Air Kerma Integrated over Beam Area in Diagnostic Radiology

   Författare :Peter Larsson; Gudrun Alm Carlsson; Jan Persliden; Bertil Axelsson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; KAP-meter; DAP-meter; PKA; kerma area product; energy dependence; calibration; Radiological physics; Radiofysik;

   Sammanfattning : The air kerma area product PKA is an important quantity used by hospital physicists in quality assurance and optimization processes in diagnostic radiology and is recommended by national authorities for setting of diagnostic reference levels. PKA can be measured using a transmission ionization chamber (kerma area product (KAP) meter) mounted on the collimator housing. LÄS MER

3. 2. Studies of clinical proton dosimetry using Monte Carlo simulation and experimental techniques

   Författare :Joakim Medin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proton dosimetry; Proton stopping power; Monte Carlo; Proton stopping-power ratios; Ionization chamber calibration; medicinsk strålningsfysik; Medical Radiation Physics;

   Sammanfattning : The present work aims at improving clinical proton dosimetry based on ionization chambers, and to bring its state of development closer to the corresponding status of conventional photon and electron dosimetry. In order to accomplish this, both theoretical and experimental methods have been used. LÄS MER
