2011 R&D 100 Winner
More than 5,000 components and 42 pending patents were incorporated into TrueBeam radiotherapy and TrueBeam STx radiosurgery systems from Varian Medical Systems, Palo Alto, Calif.
TrueBeam radiotherapy systems deliver almost every known type of radiation beam treatment in clinical use 50% faster than previous generations of Varian technology. The system redesign minimizes the time a patient has to lie immobilized on a treatment couch, giving clinics an opportunity to improve their workflow practices.
A C-shaped gantry contains the linear accelerator and rotates around the patient to deliver the beams from different angles. The gantry also supports a robotic, articulating X-ray imager that is used to fine-tune patient positioning. The couch is a precision subsystem for accurately positioning the patient over the course of multiple treatments.
Gated RapidArc radiotherapy compensates for tumor motion by synchronizing imaging with dose delivery during a continuous rotation around the patient. A new beam generation system can be configured with up to seven X-ray energies including high-intensity modes that can deliver dose rates up to 2,400 monitor units (MUs) per minute—double the maximum output of the company's earlier linear accelerators.
