What Physicians Need to Know
DICOM Support & Standards
The MAGNETOM Free.Max offers standard DICOM interoperability, including DICOM Send/Receive, Query/Retrieve, Storage Commitment, Modality Worklist, MPPS (Modality Performed Procedure Steps), and Structured Reports. It supports Enhanced MR Images (multiframe) and can convert to standard DICOM MR Images for PACS systems that do not support the enhanced format.
PACS Integration Method
Integration with PACS is achieved through standard DICOM protocols, allowing for seamless transfer and archiving of images and non-image data to remote DICOM nodes.
Reading Room Workflow Impact
The system aims to streamline workflows and improve efficiency through AI-powered features. 'myExam Companion' uses AI for user guidance, automating routine examinations and helping achieve consistent, high-quality results regardless of user experience. 'BioMatrix Select&GO' automates patient positioning, potentially reducing setup time by 30%.
AI Model Architecture (Deep Learning Approach)
The core AI technology is 'Deep Resolve,' which employs deep learning for image reconstruction. This includes targeted denoising and generating sharper, higher-resolution images from lower input signals. 'Deep Resolve Gain' uses quantitative noise maps for targeted denoising, and 'Deep Resolve Sharp' utilizes a convolutional neural network for high-resolution image generation from low-resolution input.
Processing Speed (per study)
Deep Resolve's deep learning-based reconstruction contributes to reduced scan and acquisition times. Examples show acquisition time reductions, such as from 5:16 minutes to 3:48 minutes and 2:50 minutes to 2:06 minutes for specific sequences. The dental edition reports an average workflow time under 20 minutes.
FDA Clearance Pathway
The MAGNETOM Free.Max received U.S. Food and Drug Administration (FDA) clearance in July 2021. The MAGNETOM Free.Max Dental Edition also received FDA clearance in March 2026.
Supported Modalities
The MAGNETOM Free.Max is a Magnetic Resonance Imaging (MRI) scanner with a 0.55 Tesla (0.55T) field strength. Its integrated AI tools are specifically designed to enhance MRI image acquisition, reconstruction, and workflow.
Sensitivity & Specificity Data
Specific sensitivity and specificity data for the integrated AI tools (Deep Resolve, myExam Companion) are not explicitly provided as they primarily focus on image quality enhancement and workflow automation rather than diagnostic interpretation. Initial studies on breast imaging with the Free.Max reported diagnostic image quality in all examinations.
RSNA/ACR Validation
The MAGNETOM Free.Max was first showcased at RSNA 2020, where its AI-driven features like myExam Companion and Deep Resolve were introduced.
Physician Tip
Leverage the MAGNETOM Free.Max's AI-powered Deep Resolve for improved image quality, especially in challenging areas like pulmonary and implant imaging, and to potentially reduce scan times. Utilize myExam Companion and BioMatrix Select&GO to standardize and streamline MRI examinations, ensuring consistent results across different operators and patient types, including claustrophobic or obese patients due to the 80 cm wide bore. The 0.55T field strength offers inherent benefits in reducing susceptibility and metal artifacts, which can be particularly advantageous for patients with implants. Consider its potential for new clinical applications, such as pulmonary imaging, which has historically been difficult with higher field MRI systems.
The MAGNETOM Free.Max integrates seamlessly into existing radiology ecosystems via comprehensive DICOM support, enabling efficient communication with PACS and other imaging systems. Its ability to convert Enhanced MR Images to standard DICOM MR Images ensures compatibility with various remote DICOM nodes. Remote monitoring and service solutions are also available to ensure high system uptime and proactive issue resolution.

- Compact and lightweight design allows for installation in previously challenging locations, including smaller facilities, outpatient centers, and even emergency rooms.
- AI-powered features (Deep Resolve, myExam Companion) enhance image quality, automate routine examinations, and simplify operation for users of varying skill levels.
- Good image quality, often comparable to 1.5T systems for many routine exams like brains, spines, and knees, with improved metallic implant imaging.
- Reduced scan times for certain examinations due to advanced technologies like Simultaneous Multi-Slice TSE.
Limitations
- May require more time and patience to achieve optimal results, especially for technologists accustomed to newer-generation scanners.
- Limited range of exams it can comfortably handle compared to higher-field systems, particularly struggling with small field-of-view exams (hands, wrists, fingers).
- Lack of dedicated hand/wrist and foot/ankle coils can make positioning challenging and restrictive.
- Build quality may feel somewhat lightweight, potentially not ideal for high-volume sites.
- Initial issues with frequent error messages requiring system shutdowns during long bone studies using Dixon sequences (resolved by switching to TSE).
- Some users found the new workflow unfamiliar and offering less scope for manual adjustments.

Frequently Asked Questions
The MAGNETOM Free.Max leverages AI through its Deep Resolve algorithms, which perform targeted denoising and utilize deep learning to generate sharper, higher-resolution images. This significantly boosts image quality, enabling diagnostic confidence that was previously associated with higher field strengths.
The system incorporates AI-driven workflow optimizations such as myExam Companion and BioMatrix Select&GO. myExam Companion is an AI-based user guidance system that automates routine examinations and helps achieve consistent, high-quality results, while BioMatrix Select&GO provides fully automated patient positioning for increased efficiency.
While specific details on HIPAA or GDPR compliance for AI processing are not extensively detailed in public information, Siemens Healthineers states that patient demographic data like gender, age, and ethnicity are not recorded during AI training due to data privacy reasons. The company generally adheres to data privacy principles and offers compliance manuals and privacy notices.
The MAGNETOM Free.Max, including its AI features, has received U.S. Food and Drug Administration (FDA) clearance. Its 510(k) clearance (K231617) specifically covers AI features such as Deep Resolve Boost, Deep Resolve Sharp, and Deep Resolve Swift Brain, indicating regulatory approval for these advanced imaging technologies.
MAGNETOM Free.Max, a 0.55T 'High-V MRI' system, aims to deliver image quality comparable to higher field strengths through its advanced AI and digital technologies, offering advantages for patients with implants and improved pulmonary imaging due to reduced artifacts. While other low-field systems exist, Free.Max distinguishes itself by bringing advanced AI reconstruction to a compact, cost-effective platform, broadening MRI accessibility.
The MAGNETOM Free.Max is positioned as an affordable MRI solution with a lower total cost of ownership due to reduced installation costs and a virtually helium-free infrastructure. While a specific breakdown of AI software costs isn't typically provided, the system is available through lease payments as low as $8,999* and service contracts from $3,999** monthly, which likely include ongoing software and AI updates.
The AI algorithms primarily enhance image quality and workflow, but as a 0.55T system, it may not achieve the ultra-high spatial resolution of 7T systems for highly specialized neurological or musculoskeletal imaging. While AI assists in consistent image acquisition, extensive physician oversight and traditional interpretation remain crucial for complex diagnoses, especially since some AI-enhanced images may not guarantee similar results with different setups.
The AI in MAGNETOM Free.Max is designed to perform across a broad range of body regions and protocols, and the system's wide bore accommodates diverse patient populations, including obese and claustrophobic individuals. However, while the AI significantly improves image quality at 0.55T, certain highly specialized imaging scenarios demanding the absolute highest spatial resolution, typically achieved by ultra-high field strengths, might still present comparative limitations.
