  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. Relative biological effectiveness in proton therapy: accounting for variability and uncertainties

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Jakob Ödén; Iuliana Toma-Dasu; Kjell Eriksson; Radhe Mohan; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; relative biological effectiveness; linear energy transfer; proton track-end optimisation; radiation-induced toxicity; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : Radiation therapy is widely used for treatments of malignant diseases. The search for the optimal radiation treatment approach for a specific case is a complex task, ultimately seeking to maximise the tumour control probability (TCP) while minimising the normal tissue complication probability (NTCP).

  3. 3. Dosimetric effects of breathing motion in radiotherapy

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

    Author : Anneli Edvardsson; [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 : The goal of radiotherapy is to deliver a homogeneous high dose of radiation to a tumour while minimising the dose to the surrounding healthy tissue. To achieve this, increasingly advanced treatment techniques, such as volumetric modulated arc therapy (VMAT) and proton therapy, have been developed. READ MORE

  4. 4. 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

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

    University dissertation from Göteborg

    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
