LITTLETON, Mass., Oct. 26 /PRNewswire/ -- Still River Systems' groundbreaking proton therapy system is entering the final phase of installation at the Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine in St. Louis, MO, a National Cancer Institute (NCI) Comprehensive Cancer Center. The precision of proton therapy makes it an important treatment option for patients with cancer, as it spares the healthy tissue and results in far fewer short- and long-term treatment complications. This unique device houses a revolutionary proton source based on the world's first superconducting synchrocyclotron and provides a significant reduction in the size, cost and complexity of developing and operating a proton therapy center.

This next generation proton therapy system is installed in three simple phases, in a radiation therapy room comparable in surface to that of conventional radiotherapy systems. Phase 1 consists of rigging and mounting the accelerator gantry, which holds and positions the proton source with sub-millimeter accuracy.  Phase 2 includes assembling and installing the clinical environment which comprises the 6D robotic couch, the high-accuracy treatment gantry and its applicators, the 2D/3D imaging and positioning systems and the clinical software interfaces.  The third and final phase consists of the installation of the accelerator module.   "The execution of phases 1 and 2 of the first installation went very smoothly and we are targeting 2 months to complete them in future installations," explains Bill Alvord, Vice President of Operations.

The production accelerator is now undergoing clinical commissioning, and all clinical parameters have exceeded performance expectations.  "The innovative design of our proton therapy system is simple and modular thus ensuring a lean and fast production line followed by a quick and efficient system installation," states CEO Joseph Jachinowski.
