North Star Lodge's newest linear accelerator, the Varian TrueBeam™, combines imaging and radiation into one treatment. It treats malignant tumors with unprecedented speed and accuracy.
The TrueBeam™ system, developed by Varian Medical Systems, uses a completely re-engineered control system and a multitude of technical innovations to dynamically synchronize imaging, patient positioning, motion management, and treatment delivery. The system can deliver treatments up to 50 percent faster with a dose delivery rate of up to 2,400 monitor units per minute, double the maximum output of earlier systems.
"Intelligent" automation further speeds treatments by reducing the number of steps needed for imaging, positioning and treating patients. A standard intensity-modulated treatment that would typically take ten minutes can be completed in less than two minutes. Complex radiosurgery that typically takes 40 minutes to an hour can be completed in just five to 20 minutes.
The precision of a TrueBeam™ system is measured in increments of less than a millimeter. This accuracy is made possible by the system's sophisticated architecture, which establishes a new level of synchronization between imaging, patient positioning, motion management, beam shaping, and dose delivery technologies, performing accuracy checks every ten milliseconds throughout an entire treatment.
