MAGNETOM Free.Max

The MAGNETOM Free.Max is a 0.55T superconducting Magnetic Resonance Imaging system designed for comprehensive diagnostic imaging across various anatomical regions, utilizing an 80cm bore and the syngo MR XA40A software. It employs novel hardware such as a quench-pipe-free magnet and specialized RF coils, along with advanced software features including AI-driven 'Deep Resolve' and the 'myExam Companion' workflow suite, to enhance image quality and operational efficiency for clinical diagnosis.

The MAGNETOM Free.Max is a Magnetic Resonance Imaging (MRI) system designed for diagnostic imaging, producing cross-sectional images (transverse, sagittal, coronal, oblique) of the head, body, or extremities to display internal structure and function. It operates with a 0.55T actively shielded superconducting magnet and features a wide 80 cm bore, aiming to assist physicians in diagnosis through image interpretation, with the potential use of contrast agents; this system is noted as the first 0.55T MRI intended for clinical use in the U.S. and runs on the syngo MR XA40A software platform. The device introduces significant new and modified hardware, including a magnet with no quench pipe and autoramp capabilities, a new gradient coil and power amplifier, various new RF coils (Body, Head/Neck, Spine, BioMatrix Contour L, Contour S), and an updated patient table and computer system. Software enhancements in syngo MR XA40A include "Deep Resolve Gain" and "Deep Resolve Sharp" for AI-assisted image processing, the "myExam Companion" suite (with myExam 3D camera, Cockpit, Assist, and Autopilot) for workflow optimization, and new pulse sequence features like "SWI with 3D segmented EPI" and "Accelerated Shim." Validation involved nonclinical performance testing, which included image quality assessments and SNR/uniformity measurements for coils, alongside software verification; a clinical study on 12 individuals was also conducted to evaluate Peripheral Nerve Stimulation effects.
