MAGNETOM Free.Max, MAGNETOM Free.Star

The MAGNETOM Free.Max and MAGNETOM Free.Star systems, equipped with syngo MR XA50A software, are 0.55 Tesla magnetic resonance diagnostic devices intended for producing cross-sectional images to assist in diagnosis. These devices feature updated hardware, including distinct bore sizes (80cm for Free.Max, 60cm for Free.Star) and new coils, along with enhanced software such as automated shoulder protocols and advanced perfusion imaging capabilities, to improve diagnostic workflow and imaging options.

The MAGNETOM Free.Max and the newly introduced MAGNETOM Free.Star are magnetic resonance diagnostic devices utilizing the syngo MR XA50A software platform. Both systems operate at a field strength of 0.55 Tesla and are designed to produce transverse, sagittal, coronal, and oblique cross-sectional images of the head, body, or extremities to aid in diagnosis. A primary distinction between the two is bore size, with the MAGNETOM Free.Max featuring an 80 cm patient bore and the MAGNETOM Free.Star a 60 cm bore, necessitating modifications to the Free.Star's gradient system, body coil, and system cover. Both systems can utilize contrast agents depending on the region of interest, and the derived images and physical parameters are intended for interpretation by trained physicians. This iteration introduces several hardware and software enhancements. Hardware updates include an optional dual Scanner User Interface (SUI), an upgraded myExam 3D Camera with automatic patient height, weight, and orientation detection, a new higher-resolution patient video system, and the new Contour M Coil for both systems, while the MAGNETOM Free.Max also offers a new high-load patient table. Software advancements feature the myExam Autopilot extended to shoulder examinations (myExam Shoulder Autopilot), migrated functionalities such as the EP2D_FID pulse sequence for brain perfusion imaging, Inline Perfusion for real-time parameter map calculation, and Access-i for third-party workstation connectivity. Additionally, scan assistance for off-center imaging has been modified. The performance and safety of these new and modified features were assessed through non-clinical testing, including sample clinical image evaluation, coil performance benchmarks, and software verification and validation.
