Witryna14 wrz 2007 · Metal compensators or physical modulators to deliver intensity modulated radiation therapy (IMRT) are known to change the beam energy spectrum and to produce scattered photons and contaminating electrons. Therefore the reliability of film dosimetry in compensator-based IMRT might be questioned. Conflicting data have … WitrynaIntroduction Intensity-Modulated Radiotherapy (IMRT) is becoming an increasingly routine treatment method. IMRT can be delivered by use of conventional Multileaf Collimators (MLCs) and/or physical compensators. One of the most important factors in
WitrynaMethods: TVR-IMRT, a technique designed to minimize the intensity di erence between neighboring beamlets, was used to optimize the beamlet intensity map, which was … Witryna21 paź 2004 · IMRT-compensator is generated from the ideal intensity map. For segmental MLC-IMRT treatment a discrete intensity map (right) is converted from the ideal map for MLC segmentation. The discrete “skyscraper” map displayed has 10 intensity levels. In our clinical application five to eight intensity levels are commonly …
WitrynaThis ring holds the physical compensators for the IMRT for a patient that has been calculated. So the physical device can be loaded before the treatment in each planned gantry angle. Obviously such an invasive process with a heavy load of metallic filters requires extra QA for error and to reduce the chance of a filter falling on a patient. Witryna3 paź 2024 · For compensator-based IMRT, the unique compensator design should be documented for each step or portal. Documentation of fluence distributions …
