The Lewis and Faye Manderson Cancer Center is now treating cancer patients using a new TrueBeam system from Varian Medical Systems.
This innovative technology enhances the functionality of previous linear accelerators with the delivery of highly precise image-guided radiotherapy in cancer treatment.
The TrueBeam system incorporates "intelligent" automation and high-dose delivery rates that help reduce treatment time. In many cases, patients can be in and out of the cancer center in as little as 20 minutes per day over a course of treatment. Simple treatments that once took 15 minutes or more once the patient was positioned for treatment can be completed in less than two.
"These are significant reductions in treatment time," said John Crew, MD, a radiation oncologist at the Manderson Cancer Center. "The system's pinpoint precision also reduces the chance of tumor motion during treatment, which protects healthy tissue and critical organs."
TrueBeam can be used for many forms of advanced treatments such as image-guided radiotherapy (IGRT), including intensity-modulated radiotherapy (IMRT), RapidArc® radiotherapy technology and Gated RapidArc. Radiotherapy uses lower doses or smaller fractions of the total prescribed radiation over a longer period of time.
