Brainlab and Elekta announced the installation of the 50th fully integrated system at Southampton General Hospital, which consists of Elekta’s Versa HD™ linear accelerator and ExacTrac® X-Ray, patient positioning and monitoring technology by Brainlab. Leading clinical institutions worldwide are increasingly selecting this combined solution for the precise delivery of stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT). ExacTrac adds the flexibility to image the patient at any couch or gantry angle either prior to or during treatment delivery, helping to ensure no planning compromises need to be made due to in-room verification limitations. ExacTrac allows fast and reliable independent room-based imaging, creating a highly advanced frameless system that helps to assure the patient is adequately immobilised.
