Control electronics for Multileaf Collimator for Colline Accelerator

Medical linear accelerators are the most popular devices group for curing cancer diseases because of their relatively low operating costs, high precision and when properly used, high safety. Today’s medical accelerators are developed towards easiness of use, safety, precision and generally understood efficiency . Easiness of use is provided by software like Treatment Planning Systems (TPS) and Record and Verify Systems (RVS) which are usually connected with hospitals database systems and patients timetable. Safety and precision is increased thanks to image guided radiation therapy (IGRT) and intensity modulated radiation therapy (IMRT) techniques. Patients treatment time gets shortened thanks to the application of dynamic techniques as well as volumetric intensity-modulated arc therapy (VMAT). All these together increase overall accelerator effectiveness. Nowadays medical professionals are used to friendly user interfaces but behind the scenes sophisticated algorithms, however mechanics and electronics controlling and monitoring devices perform all the hard work. Notably concentration of the most sophisticated electronics concerns Multi Leaf Collimator (MLC). This paper describes in details current architecture of electronics, process of lunch and tests of the current version of electronics for developed at the National Centre for Nuclear Research MLC as well as the outline for future device improvement.
