Radiation therapy device and informatics developer Elekta reported that it has placed two of its volumetric modulated arc therapy (VMAT) systems in Europe and that the technology is in clinical use.
The company said that The Royal Marsden Hospital in Sutton, U.K., and General Hospital in Vienna, Austria, is using the VMAT product to treat patients at their facilities.
With VMAT technology, the target is continuously radiated while the source of the beam is rotated around the patient in single or multiple arcs. By simultaneously controlling gantry position, gantry speed, leaves of the multi-leaf collimator, collimator angle and dose rate, a highly conformal dose distribution is created in less time than with other techniques, according to Elekta. Utilizing VMAT, a treatment session typically can be conducted in five minutes or less, including true 3D imaging to secure the location of the target, Elekta said.
The technology is pending 510(k) regulatory clearance in the United States.
