MAGNETOM Vida, MAGNETOM Sola, MAGNETOM Lumina, MAGNETOM Altea

The MAGNETOM Vida, Sola, Lumina, and Altea MR systems with syngo MR XA31A software are designed to provide comprehensive diagnostic imaging and interventional capabilities by producing detailed anatomical and functional images. This is achieved through a combination of new hardware, such as specialized tables and coils, and advanced software features, including novel pulse sequences, AI-based image reconstruction algorithms, and automated workflow solutions for various clinical applications.

The Siemens MAGNETOM systems, including Vida, Sola, Lumina, and Altea, when upgraded with the syngo MR XA31A software, function as magnetic resonance diagnostic devices (MRDD). Their primary purpose is to generate various cross-sectional images (transverse, sagittal, coronal, oblique), spectroscopic images, and spectra of the head, body, or extremities. These outputs, interpretable by trained physicians, display internal structures and functions to assist in diagnosis, with the option of using contrast agents. The systems are also designed for imaging during interventional procedures when used with MR-compatible equipment. This iteration introduces a range of new and modified hardware and software components compared to its predicate device. Key hardware advancements include the Nexaris Dockable Table for intraoperative and interventional imaging, the Nexaris Head Frame, new coils such as the Nexaris Spine 36 and Flex Loop Large, a new computer system, and a modified Beat Sensor for contactless cardiac triggering. Software enhancements are extensive, featuring new pulse sequences like SVS_EDIT for acquiring two different spectra in a single sequence, BEAT_FQ_nav for navigator echo-based respiratory gating in 4D flow imaging, HASTE_interactive for interactive parameter changes, and GRE_WAVE for larger acceleration factors in 3D susceptibility-weighted imaging. Other notable software additions include the Prostate Dot Engine for assisted prostate imaging workflows, injector coupling for synchronized contrast injection, optimized high bandwidth inversion recovery pulses for myocardial tissue imaging, the AbsoluteShim procedure, Deep Resolve Sharp and Deep Resolve Gain algorithms for image enhancement using convolutional neural networks, and improved 3D ASL sequences providing relCBF and BAT maps. Non-clinical testing confirmed that these new and modified features perform as intended, demonstrating an equivalent safety and performance profile.
