In those early days, treatment planning was a meticulous process involving manual calculations and in-house software for dose computation. Radiosurgery necessitated the attachment of frames to patients' heads, followed by CT imaging and hand-drawing contours using wax pencils. Edited images were then uploaded to a Macintosh computer equipped with a light box and electrostatic digitizer. After an hour of set up, the limited dose rates available at the time meant treatment itself took at least an hour. Between all these constraints, the hospital could treat no more than three individual tumors in a day.<\/p>\n<p>&nbsp;<\/p>\n<p>With the steady acquisition of increasingly advanced technology and systems in the ensuing years, we have seen progressive improvements in calculation speed, dose strength, and accuracy to realize ever more effective treatments. Today, the DROAS encompasses top-caliber faculty and staff who employ state-of-the-art technologies to treat over 1,000 patients annually. We offer a comprehensive array of world-class therapies, including stereotactic radiosurgery, extra-cranial radiation therapy, gated radiation therapy, real-time target monitoring, brachytherapy, and cutting-edge image-guided radiation therapies such as CT imaging, VisionRT applications, 4D simulation scanning, and adaptive radiation planning.<\/p>\n<p>&nbsp;<\/p>\n<h2>A History of Innovation<\/h2>\n<ul>\n<li>1973: 1<sup>st<\/sup> Betatron X-ray machine in New England<\/li>\n<li>1997: 1<sup>st<\/sup> 3D treatment planning in New England<\/li>\n<li>2003: 1<sup>st<\/sup> IMRT in New England<\/li>\n<li>2004: world\u2019s first demonstration of cardiac gating<\/li>\n<li>2004: 1<sup>st<\/sup> to publish findings on VisiCoil in humans<\/li>\n<li>2005: 1<sup>st<\/sup> in New England to offer daily prostate IGRT<\/li>\n<li>2013: 1<sup>st<\/sup> Single-isocenter, multi-focal SRS<\/li>\n<li>2014: 2<sup>nd<\/sup> in US &amp; 4<sup>th<\/sup> in world to acquire TrueBeam<\/li>\n<li>2017: 1<sup>st<\/sup> in northern New England w\/Space OAR<\/li>\n<li>2020: among 1<sup>st<\/sup> in US to offer MR-LINAC<\/li>\n<li>2022: 1<sup>st<\/sup> in world to integrate Cherenkov w\/SGRT<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Founded in the early 1990s, our department has pioneered advancements in radiation treatment planning and radiosurgery.
