  1. 1. Deep-learning based prediction model for dose distributions in lung cancer patients

    University essay from Stockholms universitet/Fysikum

    Author : Terese Hellström; [2021]
    Keywords : ;

    Abstract : Background To combat one of the leading causes of death worldwide, lung cancer treatment techniques and modalities are advancing, and the treatment options are becoming increasingly individualized. Modern cancer treatment includes the option for the patient to be treated with proton therapy, which can in some cases spare healthy tissue from excessive dose better than conventional photon radiotherapy.

  3. 2. Robust Optimization for Uncertain Radiobiological Parameters in Inverse Dose Planning

    University essay from KTH/Optimeringslära och systemteori

    Author : Jennie Falk; [2015]
    Keywords : ;

    Abstract : Cancer is a common cause of death worldwide with radiotherapy as one of the most used treatments. Radiation treatment plans are normally optimized using constraints on the maximum dose to tumours and minimum dose to surrounding healthy structures. READ MORE

  4. 3. A comparative treatment planning study of radiotherapy of clinical liver- and stomach-cancer cases with either photon or proton beams

    University essay from Stockholms universitet/Fysikum

    Author : Gracinda Mondlane; [2014]
    Keywords : ;

    Abstract : There has been an increasing interest in proton beam therapy (PBT) in recent years related to the advantageous depth-dose characteristics of proton beams compared to what is achievable with standard external photon beam radiotherapy (RT). With PBT, improved target dose conformity can be achieved together with a reduction in the dose to the organs at risk (OARs). READ MORE

  5. 4. Development of a test bench for Gamma Knife Optimization

    University essay from KTH/Optimeringslära och systemteori

    Author : Victoria Svedberg; [2014]
    Keywords : ;

    Abstract : The dose distribution in the Gamma Knife (developed and produced by Elekta) is optimized over the weights (or Beam-on time) using different models other than the radiosurgical one used in Leksell Gamma Plan . These are based on DVH, EUD, TCP and NTCP. READ MORE

  6. 5. Clinical Investigations of Image Guided Radiation Therapy for Prostate Cancer with an On-Board Imager

    University essay from Medicinsk strålningsfysik (tills m KI)

    Author : Maria Lindskog; [2008]
    Keywords : Cone-beam CT; IGRT; Adaptive radiotherapy;

    Abstract : The daily uncertainty concerning tumor localization is one of the major problems during the course of radiation therapy. Image guided-radiation therapy (IGRT) can be used to improve the localization and adjustment of the planning target volume. READ MORE
