  1. 6. Absorbed dose and biological effect in light ion therapy

    Author : Malin Hollmark; Irena Gudowska; Oliver Jäkel; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Light ion therapy; absorbed dose calculation; analytical pencil beam model; Monte Carlo; radiobiological modeling; Radiological physics; Radiofysik; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : Radiation therapy with light ions improves treatment outcome for a number of tumor types. The advantageous dose distributions of light ion beams en-able exceptional target conformity, which assures high dose delivery to the tumor while minimizing the dose to surrounding normal tissues.

  3. 8. Absorbed Dose Determination and Characteristics of Degraded Electron Beams: Application to Intraoperative Radiation Therapy

    Author : Peter Björk; Internmedicin - epidemiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; absorbed dose distribution; output factor; stopping-power ratio; beam characteristics; Monte Carlo calculation; electron beam dosimetry; applicator system; radiation therapy; linear accelerator; intraoperative radiotherapy;

    Abstract : The aim of this work was to quantify limitations of and uncertainties in commonly used dosimetric techniques for relative absorbed dose determination in degraded electron beams, such as those encountered in intraoperative radiation therapy (IORT) and small-electron-field radiotherapy. Three different detector types were investigated with regard to measurements of output factors and relative absorbed dose distributions: (1) a parallel-plate ionization chamber, (2) a p-type silicon diode detector and (3) a diamond detector.

  4. 9. Beam Modelling for Treatment Planning of Scanned Proton Beams

    Author : Peter Kimstrand; Bengt Glimelius; Erik Traneus; Nina Tilly; Anders Ahnesjö; Thomas Bortfeld; Uppsala universitet; []
    Keywords : Radiation sciences; proton therapy; treatment planning; beam modelling; dose calculation; Monte Carlo; Strålningsvetenskap;

    Abstract : Scanned proton beams offer the possibility to take full advantage of the dose deposition properties of proton beams, i.e. the limited range and sharp peak at the end of the range, the Bragg peak. READ MORE

  5. 10. Pharmacometric Approaches to Improve Dose Individualization Methods in Hemophilia A

    Author : João A. Abrantes; Mats Karlsson; Elisabet I. Nielsen; Siv Jönsson; Ron Mathôt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bayesian forecasting; coagulation factor VIII; dose adaptation; hemophilia haemophilia A; inter-occasion variability; NONMEM; pharmacodynamics; pharmacokinetics; pharmacometrics; therapeutic drug monitoring; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Hemophilia A is a bleeding disorder caused by the lack of functional coagulation factor VIII (FVIII). The overall aim of this thesis was to improve dose individualization of FVIII replacement therapy in hemophilia A using pharmacometric approaches. READ MORE
