  5. 4. Relative biological effectiveness in proton therapy: accounting for variability and uncertainties

    Författare :Jakob Ödén; Iuliana Toma-Dasu; Kjell Eriksson; Radhe Mohan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; relative biological effectiveness; linear energy transfer; proton track-end optimisation; radiation-induced toxicity; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : Radiation therapy is widely used for treatments of malignant diseases. The search for the optimal radiation treatment approach for a specific case is a complex task, ultimately seeking to maximise the tumour control probability (TCP) while minimising the normal tissue complication probability (NTCP).

  7. 5. Implementation of MRI gel dosimetry in radiation therapy

    Författare :Sven Bäck; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; uncertainty; detector; dosimeter; ferrous ions; gel dosimetry; magnetic resonance imaging; monomers; polymerisation; proton; treatment planning verification; radiation therapy; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. LÄS MER
