Dr. Shah's clinical team compared a RapidArc treatment plan with one for conventional IMRT and found that the RapidArc plan spared more of Kelver's salivary glands and the rest of his oral cavity.

According to Dr. Shah, RapidArc technology is now being used to treat prostate, lung, and brain cancer. "A father and son, 76 and 43 years of age, are among the patients currently undergoing RapidArc treatment for prostate cancer," he said. "We looked at RapidArc plans as compared with conventional IMRT for these types of cases, and concluded that the RapidArc approach does a better job of protecting the rectum and the bladder. And with treatments being completed so quickly, these two can get in and out of the office faster and spend more quality time together."
Another patient, Raymond Kelly, is a 72-year-old man with stage 3 lung
cancer that has spread to his lymph nodes on both sides. "With earlier
forms of radiation therapy, once a tumor spreads to this degree, you have
to limit the dose because of all the healthy lung tissue you would
otherwise damage during treatment," Dr. Shah explained. "The RapidArc
