1. 1. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Sara Falk; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : 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

3. 2. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Mizgin Coskun; [2022]
   Keywords : Medicine and Health Sciences;

   Abstract : 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

4. 3. Breathing Effects in Proton Scanning for Hodgkin's Lymphoma

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : John Nilsson; [2022]
   Keywords : Medicine and Health Sciences;

   Abstract : 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).

5. 4. Toxicity of Pulsed Beams in Radiation Therapy from a Physio-Chemical Perspective

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Karin Källén; [2021]
   Keywords : FLASH; radiotherapy; ultra high; dose rates; radiolysis; cancer; medical; FLASH; strålbehandling; ultrahög; doshastighet; radiolys; cancer; medicinsk;

   Abstract : 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

6. 5. Supervised Learning for Prediction of Tumour Mutational Burden

   University essay from KTH/Matematisk statistik

   Author : Joanna Hargell; [2021]
   Keywords : Supervised Learning; Tumour Mutational Burden; Generalized Linear Models; Decision trees; Support Vector Machines; statistik; tillämpad matematik; statistisk inlärning; mutationsbörda;

   Abstract : 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
