<qa>  What is the name of the MAGNETOM product used for intraoperative imaging?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.
