MAGNETOM Cima.X

The MAGNETOM Cima.X is an advanced magnetic resonance diagnostic device designed to enhance diagnostic imaging of the head, body, and extremities through upgraded hardware, including a new 3D camera and modified gradient coil. It employs syngo MR XA61A software featuring novel AI-driven image reconstruction techniques like Deep Resolve Boost and new pulse sequences such as MR Fingerprinting, aiming to improve image quality and diagnostic capabilities as validated by nonclinical testing and supported by existing clinical literature.

The MAGNETOM Cima.X, operating with syngo MR XA61A software, is a magnetic resonance diagnostic device designed to generate cross-sectional images (transverse, sagittal, coronal, oblique), spectroscopic images, and spectra of the head, body, or extremities. Its purpose is to display internal structures and functions, potentially deriving other physical parameters to aid physicians in diagnosis, with the option of using contrast agents and supporting imaging during MR-compatible interventional procedures; the system incorporates new hardware components like a 3D camera, and modified elements including host computers, gradient coil, and body coil, alongside a suite of new and enhanced software features. Key software advancements in the MAGNETOM Cima.X include new applications such as Deep Resolve Boost (for HASTE and EPI Diffusion), Open Recon, Ghost reduction (DPG), and SAMER, alongside the integration of MR Fingerprinting, with Deep Resolve features leveraging artificial intelligence trained on extensive datasets (tens of thousands to over a million slices) covering diverse body parts and imaging conditions, using metrics like PSNR and SSIM for validation; while no new clinical trials were conducted, the system's performance and safety were evaluated through nonclinical testing, including software verification, image quality assessments with sample clinical images, hardware bench tests, and adherence to international safety and EMC standards, supported by existing clinical publications for specific features.
