  1. 21. Evaluation of margins and plan robustness for proton therapy of unilateral tonsil cancer.

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Institutionen för strålningsvetenskaper

    Author : Josefine Grefve; [2021]
    Keywords : ;

    Abstract : During proton therapy both target volumes and healthy tissue, including organs at risk (OARs), receives radiation dose. Thus, radiotherapy is a trade-off between good target coverage and OAR sparing. For protons, most of the dose is deposited right before it is stopped, a phenomenon termed the Bragg peak. READ MORE

  3. 22. Prediction of Dose Probability Distributions Using Mixture Density Networks

    University essay from KTH/Matematisk statistik

    Author : Viktor Nilsson; [2020]

    Abstract : In recent years, machine learning has become utilized in external radiation therapy treatment planning. This involves automatic generation of treatment plans based on CT-scans and other spatial information such as the location of tumors and organs. READ MORE

  4. 23. Impact of MLC shape smoothing on VMAT plan complexity and agreement between planned and delivered dose

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Linnéa Strandell; [2020]
    Keywords : Medicine and Health Sciences;

    Abstract : Background/Purpose: The aperture shape controller (ASC) was introduced in the Eclipse treatment planning system to reduce plan complexity by counteracting irregular multileaf collimator (MLC) shapes. This should lead to decreased difference between the planned and measured dose distribution. READ MORE
