  1. 1. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Caroline Olsson; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dose and side effect data; dose-volume response; fractionation effect; LQ model; sequential two-phase radiotherapy; head and neck cancer; parotid gland; xerostomia; pelvic radiotherapy; gynecological cancer; pubic bone; pain; data integration;

    Abstract : Although modern radiation therapy techniques have the ability to conform the dose distribution of ionizing radiation tightly around the volume to be treated, unwanted irradiation to surrounding organs remains a problem. The probability of a side effect arising in the normal tissue of a patient after radiation therapy can be modelled by sigmoid mathematical functions known as normal tissue complication probability (NTCP) models.

  2. 2. Dosimetric effects of breathing motion in radiotherapy

    University dissertation from Lund University, Faculty of Science, Department of Medical Radiation Physics

    Author : Anneli Edvardsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018-09]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiotherapy; breathing motion; DIBH; interplay effects; VMAT; proton therapy; breast cancer; Hodgkin’s lymphoma; liver; dosimetry; treatment planning; medical physics;

    Abstract : Cirka hälften av alla som drabbas av cancer i Sverige genomgår strålbehandling, där högenergetisk strålning används för att tillintetgöra cancertumören. Inför strålbehandlingen görs en datortomografiundersökning, vilket är en form av röntgenundersökning som ger snittbilder av patienten i tre dimensioner. READ MORE

  3. 3. Predicting Normal Tissue Complications after External Beam Radiation Therapy

    University dissertation from Lund University, Faculty of Science, Department of Medical Radiation Physics

    Author : Caroline Olsson; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NTCP; fractionation effects; radiobiological modelling; pubic bone pain;

    Abstract : Although modern external beam radiation (EBRT) therapy has the ability to conform the dose tightly around the volume to be treated, unwanted irradiation to surrounding normal tissue is still a problem. The probability of a side effect arising in normal tissue after EBRT is commonly modelled by an s-shaped dose-volume response curve where dose or volume are plotted against response (i. READ MORE

  4. 4. Imaging diffusional variance by MRI [public] : The role of tensor-valued diffusion encoding and tissue heterogeneity

    University dissertation from Lund University, Faculty of Science, Department of Medical Radiation Physics

    Author : Filip Szczepankiewicz; Lunds universitet.; Lund University.; [2016-11]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Diffusion är den slumpmässiga rörelse hos partiklar som drivs av deras kinetiska energi. Den är oftast osynlig för blotta ögat, men den utgör en viktig funktion för vår överlevnad. READ MORE

  5. 5. Modeling of radiative processes in organic scintillators

    University dissertation from Göteborg

    Author : Jenny Nilsson; Göteborgs universitet.; Gothenburg University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents the development of a Monte Carlo calibration of a whole body counter (WBC), consisting of four large plastic (organic) scintillators, used for determine the body burden of gamma-emitting radionuclides. A scintillator emits optical photons after energy has been deposited by an ionizing particle in the scintillator material. READ MORE
