Swiss doctors have executed the country’s first clinical treatments using RapidArc™ technology from Varian Medical Systems. Clinicians carried out each patient’s scheduled radiotherapy course using RapidArc. IOSI (Istituto Oncologico della Svizzera Italiana) has become the first non-university European hospital to treat with the use of Varian’s RapidArc. The technology delivers a volumetric intensity-modulated radiation therapy in a single or multiple arcs of the treatment machine around the patient, delivering advanced image-guided IMRT much faster than the conventional IMRT.
