 Recently, Viewray Inc Cleveland, OH has released the RenaissanceTM System 1000, which consists of the combination of an open, split solenoid 0.35 T MRI scanner that is equipped for parallel imaging with a 60Co gamma-ray radiation treatment unit. The MRI scanner is required to be a low field unit to allow for imaging with spatial integrity by limiting magnetic susceptibility artifacts due to the patient and to prevent significant perturbations of the dose distribution. The 0.35 T magnet is a variant of the Siemens MAGNETOM product used for intraoperative imaging.
