2. Impact of MLC shape smoothing on VMAT plan complexity and agreement between planned and delivered dose
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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

4. Robust optimization of radiotherapy treatment plans considering time structures of the delivery
University essay from Uppsala universitet/Avdelningen för datalogiAbstract : 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

5. Real-time dynamic MLC tracking for inversely optimised arc radiotherapy
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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
