  1. 1. Reinforcement learning applied to MLC tracking

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Adithya Raju Ganeshan; [2021]
    Keywords : Reinforcement Learning; Multileaf Collimator; Magnetic Resonance Imaging; Adaptive Radiotherapy;

    Abstract : Radiotherapy has become an ever more successful treatment option for cancer.Advances in imaging protocols combined with precise therapy devices suchas linear accelerators contribute towards millimeter precision of treatmentdelivery with far fewer side effects. READ MORE

  3. 2. 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

  5. 4. Robust optimization of radiotherapy treatment plans considering time structures of the delivery

    University essay from Uppsala universitet/Avdelningen för datalogi

    Author : Erik Orvehed Hiltunen; [2018]

    Abstract : Cancer is the second largest mortal disease in Sweden, and high efforts are made to develop the treatment of cancer. One of the main treatment methods is radiotherapy, which uses ionizing radiation to damage the cancerous cells. This has the chance of stopping the cell reproduction, and the goal is to reduce the tumor and stop the tumor growth. READ MORE

  6. 5. Real-time dynamic MLC tracking for inversely optimised arc radiotherapy

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Marianne Falk; [2009]
    Keywords : Strålterapi; Medicine and Health Sciences;

    Abstract : Purpose: Radiotherapy of moving tumours is a great challenge in cancer treatment. The moving target will lead to “dose-smearing” of the planned dose distribution and a need for larger margins. To reduce the dose to the surrounding healthy tissue, while still ensuring full coverage of the target, other methods for motion compensation is needed. READ MORE
