Elekta Software Making Strong Inroads in Clinics Providing Proton Therapy for Patients with Cancer

VILLIGEN, Switzerland, March 29, 2011 /PRNewswire/ -- The Paul Scherrer Institute (PSI) in Switzerland and Elekta are collaborating to further develop treatment planning and oncology information systems (OIS) for proton therapy, a form of external beam radiation that uses protons instead of X-rays or electrons to treat certain types of cancer and other diseases.

PSI integrated Elekta's XiO® treatment planning system and MOSAIQ® OIS into its Centre for Proton Therapy to manage the flow of information and image data between treatment delivery, treatment planning, treatment simulation and the patient's electronic medical record. In clinical use for nearly a decade, XiO is in use at more proton and carbon ion facilities than any commercial vendor with a similar product. Elekta recently received 510(k) clearance from the U.S. Food and Drug Administration for XiO to plan spot scanning, a proton therapy delivery method that involves constructing a highly conformal placement of dose to the tumor by using thousands of small individual beamlets instead of a single large beam.

"Through XiO, Elekta provides a combination of advanced tools for scanned proton beam therapy. Elekta also provides a clear road map to further develop intensity modulated, image guided and adaptive proton therapy," says Antony Lomax, Ph.D., Professor and Head of Medical Physics at the Center for Proton Therapy at PSI. "A deciding factor in entering into this relationship was Elekta's willingness to leverage the significant experience of our team to increase the capabilities of XiO proton planning."
