  1. 21. Quality Assurance in Radiotherapy - Development and evaluation of new tools for improved patient safety

    Författare :Fredrik Nordström; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; monitor unit verification; in vivo dosimetry; real-time verification; gel dosimetry; 4D dosimetry; IMRT; VMAT; data integrity; radiotherapy; Quality assurance;

    Sammanfattning : Preparation for radiotherapy is a complex procedure that involves many different technologies and groups of professionals. The rapid development and introduction of new technologies throughout the last decade have made it possible to deliver highly conformal, individually-shaped dose distributions with high accuracy.

  3. 22. Patient Outcomes after Radiotherapy of Prostate Cancer. Impact of Absorbed Dose and Treated Volume

    Författare :Elisabeth Rasmusson; LUCC: Lunds universitets cancercentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer diagnosis; radiotherapy; brachytherapy; external beam; Dose- response; side effects; erectile dysfunction; lymphedema; hip osteoarthritis; Fractionation;

    Sammanfattning : Abstract Backgound Prostate cancer is the most common form of cancer in men in Sweden. Radiotherapy, including external beam radiation therapy (EBRT) and brachytherapy (BT), is important treatment alternatives to surgery and active surveillance. LÄS MER

  4. 23. Motion management optimization in radiotherapy : From the most common to the most uncommon patient

    Författare :Annika Mannerberg; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; Motion management; SGRT; SGRT; Motion management; Radiotherapy; Fysicumarkivet A:2023:Mannerberg;

    Sammanfattning : In radiotherapy (RT), the treatment is thoroughly planned and optimized to fulfil the goal of delivering a high dose to the target, while sparing as much normal tissue as possible. This implies that the patient position and anatomy should be the same as they were during the planning image acquisition. LÄS MER

  5. 24. Time, dose and fractionation: accounting for hypoxia in the search for optimal radiotherapy treatment parameters

    Författare :Emely Kjellsson Lindblom; Iuliana Toma-Dasu; Peter Wersäll; David J Carlson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hypoxia; radiobiological modelling; radiotherapy; functional imaging; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : The search for the optimal choice of treatment time, dose and fractionation regimen is one of the major challenges in radiation therapy. Several aspects of the radiation response of tumours and normal tissues give different indications of how the parameters defining a fractionation schedule should be altered relative to each other which often results in contradictory conclusions.

  7. 25. MRI based radiotherapy planning and pulse sequence optimization

    Författare :Jens Sjölund; Hans Knutsson; Mats Andersson; Michael Felsberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Radiotherapy plays an increasingly important role in cancer treatment, and medical imaging plays an increasingly important role in radiotherapy. Magnetic resonance imaging (MRI) is poised to be a major component in the development towards more effective radiotherapy treatments with fewer side effects. LÄS MER
