1. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE

2. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. READ MORE

3. Breathing Effects in Proton Scanning for Hodgkin's Lymphoma
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/Background Proton beam scanning (PBS) for mediastinal Hodgkin's Lymphoma (HL) is limited when treating in free-breathing (FB) due to breathing motion in the thoracic region. Tumour motion and the time structure of the beam delivery will cause interplay and dose blurring effects, resulting in discrepancies of dose in the planned dose distribution both inside and at the edges of tumour volume (TV).

4. Toxicity of Pulsed Beams in Radiation Therapy from a Physio-Chemical Perspective
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : A significant portion of cancer patients receive radiotherapy as part of their curative or palliative treatment plan. Radiotherapy is however greatly limited by radiation induced toxicities in healthy tissue surrounding the tumour, which can lead to long-term or acute complications for a patient. READ MORE

5. Supervised Learning for Prediction of Tumour Mutational Burden
University essay from KTH/Matematisk statistikAbstract : Tumour Mutational Burden is a promising biomarker to predict response to immunotherapy. In this thesis, statistical methods of supervised learning were used to predict TMB: GLM, Decision Trees and SVM. READ MORE
