  2. 1. Dosimetry Studies of Different Radiotherapy Applications using Monte Carlo Radiation Transport Calculations

    Author : Shirin Abbasinejad Enger; Hans Lundqvist; Anders Ahnesjö; Irena Gudowska; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; External Beam Radiotherapy; Gadolinium Neutron Capture Therapy; Gadolinium Neutron Capture Brachytherapy; Targeted Radionuclide therapy; Detector Response Modelling; Monte Carlo Simulation.; Radiological physics; Radiofysik;

    Abstract : Developing radiation delivery systems for optimisation of absorbed dose to the target without normal tissue toxicity requires advanced calculations for transport of radiation. In this thesis absorbed dose and fluence in different radiotherapy applications were calculated by using Monte Carlo (MC) simulations. READ MORE

  4. 2. Out-of-field doses from proton therapy and doses from CBCT imaging : Risk of radiation-induced second cancer from modern radiotherapy

    Author : Oscar Ardenfors; Irena Gudowska; Alexandru Dasu; Cathrine Jonsson; Pawel Olko; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The use of ionizing radiation for treatment of cancer diseases is continuously increasing as patient survival is improving and new treatment techniques are emerging. While this development is beneficial for curing primary tumors, concerns have been raised regarding the unwanted dose contribution to healthy tissues of patients and the associated risk of radiation-induced second cancer (RISC).

  5. 3. Secondary doses to healthy tissues from radiotherapy and modern imaging techniques

    Author : Oscar Ardenfors; Irena Gudowska; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The use of ionizing radiation for treatment of cancer diseases is continuously increasing giving rise to several new questions and concerns. One of the most important aspects of this is the associated dose imparted to healthy tissues. This unwanted dose contribution is a result of both radiotherapy procedures and diagnostic imaging.

  6. 4. Monte Carlo particle transport codes for ion beam therapy treatment planning : Validation, development and applications

    Author : Till Tobias Böhlen; Irena Gudowska; Oliver Jäkel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; ion beam therapy; treatment planning; cancer therapy; microdosimetry; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : External radiotherapy with proton and ion beams needs accurate tools for the dosimetric characterization of treatment fields. Monte Carlo (MC) particle transport codes, such as FLUKA and GEANT4, can be a valuable method to increase accuracy of dose calculations and to support various aspects of ion beam therapy (IBT), such as treatment planning and monitoring.

  7. 5. Interlaced proton grid therapy: development of an innovative radiation treatment technique

    Author : Thomas Henry; Irena Gudowska; Tony Lomax; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; grid therapy; spatially fractionated therapy; interlacing; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Spatially fractionated radiotherapy, also known as grid therapy (GRID), has been used for more than a century to try to treat several kinds of lesions. Yet, the grid technique remains a relatively unknown and uncommon treatment modality nowadays. READ MORE
