MAGNETOM Free.Max; MAGNETOM Free.Star

The MAGNETOM Free.Max and MAGNETOM Free.Star systems, now featuring syngo MR XA60A software, are advanced magnetic resonance diagnostic devices designed for detailed anatomical and functional cross-sectional imaging, with the Free.Max model newly indicated for MR-guided interventional procedures. These capabilities are realized through updated hardware components like the Contour Knee coil and Respiratory Sensor, and significant software enhancements including the AI-based 'Deep Resolve Boost' for improved image quality and specialized applications such as 'myExam RT Assist' for radiotherapy support.

The MAGNETOM Free.Max and MAGNETOM Free.Star, operating with the new syngo MR XA60A software, are magnetic resonance diagnostic devices (MRDD) designed to produce detailed cross-sectional images (transverse, sagittal, coronal, oblique) of the head, body, or extremities, aiding physicians in diagnosis. These images can display internal structures and functions, and derived physical parameters can also be produced, with contrast agents used as needed. A key update for the MAGNETOM Free.Max is its extended indication for use in MR imaging during interventional procedures, utilizing MR-compatible devices like biopsy needles, a capability enabled by the new software. The MAGNETOM Free.Star maintains its established indications for use, producing images that assist in diagnosis when interpreted by a trained physician. These systems introduce several hardware and software enhancements compared to their predecessors using syngo MR XA50A software. New hardware includes the Contour Knee coil and a Respiratory Sensor, while the myExam 3D Camera, Host computer, and MaRS (Magnetom Remote Service) have been modified. Software innovations are extensive, featuring new applications such as Injector coupling, Respiratory Sensor Support, myExam Autopilot Hip, Complex Averaging, and the AI-driven 'Deep Resolve Boost' for image enhancement, which was trained on over 26,000 2D slices from 1.5T and 3T MRI scanners. For the MAGNETOM Free.Max specifically, new software includes myExam RT Assist, HASTE_Interactive, BEAT_Interactive, and Needle Intervention AddIn. Modified software features common to both systems include Deep Resolve Sharp, Deep Resolve Gain, and SMS Averaging. Non-clinical performance testing, including sample clinical images and software verification, demonstrated that these new and modified features perform as intended.
