Summary: | The use of Volumetric Modulated Arc Therapy (VMAT) is expected to increase, largely due to development of helical tomotherapy. VMAT minimises the occurence of hotspots and inadiation of critical organs, providing more uniform dose while sparing critical organs. Two important characteristics of VMA T are its dynamic nature and dosimetric variability in radiation delivery. These present considerable challenge for clinical physicists as the implementation of the process contains a number of sources of uncertainty and thus require robust QA. |
