  1. 1. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Thi Guldhill; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE

  3. 2. osimetric impact of system spe cific geometric distortion on head and neck treatment plans in MRI only based radiation therapy

    University essay from

    Author : Jesper Brovall; [2022-01-13]
    Keywords : Medical physics; Dosimetry; MRI; Radiation therapy;

    Abstract : Background/ purpose: Because of the superior soft tissue contrast, in comparison with computed tomography (CT) data, magnetic resonance imaging (MRI) is of high interest to include in a larger extent in the ra diation therapy (RT) process. In an MRI only workflow, the CT scan is excluded and a synthetic CT is used for treatment plan ning. READ MORE

    Author : Frida Westerbergh; [2019]
    Keywords : Physics and Astronomy;

    Abstract : BACKGROUND: Radioiodine (131I) has been used in thyroid cancer treatments for many years, and has demonstrated good results with regards to disease management. Radioiodine therapy is however partially empirical, as not very much is known concerning radiation dosimetry. READ MORE

  6. 5. Breathing interplay effects during Tomotherapy. A 3D gel dosimetry study

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Anna Ljusberg; [2013]
    Keywords : Medicine and Health Sciences;

    Abstract : Tomotherapy delivers intensity modulated radiation therapy, IMRT, which enables highly advanced treatment plans with homogenous absorbed dose coverage of the target with sharp dose gradients to spare surrounding healthy tissue. Helical tomotherapy consists of a linear accelerator mounted on a rotating gantry, the construction is similar to a CT although the energy is in the MV-range instead of kV and extra collimators and beam stopper are inserted [1-3].
