MASSACHUSETTS GENERAL HOSPITAL SELECTS ELEKTA AS NEW VENDOR FOR COMPLETE CANCER TREATMENT SOLUTION

PRESS RELEASE Stockholm, Sweden, October 2, 2009Massachusetts General Hospital (MGH) Cancer Center has purchased four radiation therapy treatment systems from Elekta, including three Elekta Infinity and one Elekta Synergy® S. The order, which includes information management software, will enable the facility to offer patients a complete cancer treatment solution from the company.The three Infinity systems position MGH to take advantage of Volumetric Modulated Arc Therapy (VMAT), a new radiation therapy technique that allows clinicians to deliver tightly focused radiation treatments in less time. A treatment session typically can be conducted in five minutes or less and delivered with single or multiple arcs depending upon the patients needs.Elekta Infinity also supports all forms of Intensity Modulated Radiation Therapy (IMRT) and Image Guided Radiation Therapy (IGRT).MGH also purchased Elekta Synergy S, a state-of-the-art digital linear accelerator with integrated imaging capabilities. The facility will use Elekta Synergy S to perform Stereotactic Radiosurgery (SRS) and Stereotactic Radiotherapy (SRT) throughout the body, as well as hypofractionated treatments utilizing IGRT and VMAT.The four treatment machines also feature the HexaPOD™ evo RT system, a vision guided patient positioning platform with six degrees of freedom. Six degrees of freedom means that the system can detect and correct misalignments in patient positioning —making it ideal for the very high accuracy required during critical radiation treatments.
