  4. 3. Dose Determination at kV X-ray Qualities Using Different Protocols

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Elias Dellow; [2007]
    Nyckelord :Strålterapi; Medicine and Health Sciences;

    Sammanfattning : Absorbed dose was determined under reference conditions at four x-ray qualities; 30, 80, 120 and 200 kV using five different dosimetry protocols and codes of practice; IAEA TRS-398, AAPM, IPEMB, NCS and DIN. The dose determined by the IAEA protocol was chosen as reference. LÄS MER
