  1. 1. Development of a Whole Body Atlas for Radiation Therapy Planning and Treatment Optimization

    Författare :Sharif Qatarneh; Anders Brahme; Bengt Lind; Anders Ahnesjö; Stockholms universitet; []
    Nyckelord :3D whole body atlas; lymph node topography; matching transformation; radiation therapy planning; radiobiological optimization; segmentation; target volume definition; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : The main objective of radiation therapy is to obtain the highest possible probability of tumor cure while minimizing adverse reactions in healthy tissues. A crucial step in the treatment process is to determine the location and extent of the primary tumor and its loco regional lymphatic spread in relation to adjacent radiosensitive anatomical structures and organs at risk.

  3. 3. Improved dose response modeling for normal tissue damage and therapy optimization

    Författare :Magdalena Adamus-Górka; Bengt K. Lind; Anders Brahme; Panayiotis Mavroidis; Randall K. Ten Haken; Stockholms universitet; []
    Nyckelord :Normal tissue complications; radiobiological models; dose-response; volume effect; spinal cord; effective FSU size; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : The present thesis is focused on the development and application of dose response models for radiation therapy. Radiobiological models of tissue response to radiation are an integral part of the radiotherapeutic process and a powerful tool to optimize tumor control and minimize damage to healthy tissues for use in clinical trials.

  4. 4. Development of improved radiation therapy techniques using narrow scanned photon beams

    Författare :Björn Andreassen; Anders Brahme; Håkan Danared; Roger Svensson; Antony Lomax; Stockholms universitet; []
    Nyckelord :IMRT; Scanned photon beams; PET-CT treatment verification; Monte Carlo; NATURAL SCIENCES; NATURVETENSKAP; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : The present thesis is focused on the development and application of narrow scanned high energy photon beam for radiation therapy. The introduction of physically and biologically optimized intensity modulated radiation therapy (IMRT) requires a flexible and accurate dose delivery method to maximize the treatment outcome.

  5. 5. Biological optimization of angle of incidence and intensity modulation in breast and cervix cancer radiation therapy

    Författare :Brigida Costa Ferreira; Anders Brahme; Roger Svensson; Ion Christian Chiricuta; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biological treatment planning; angle of incidence optimization; intensity modulation; breast and cervix cancer; Radiation biology; Strålningsbiologi;

    Sammanfattning : Biological treatment optimization aim at improving radiation therapy by accounting for the radiobiological tumour and normal tissues response properties when optimizing the dose delivery. Generally traditional methods, using only dosimetrical measures, disregard the nonlinear radiation response of different tumours and normal tissues. LÄS MER
