We are currently developing several quantitative MRI phantoms, with initial releases planned from Spring 2026. If you’re interested in early access, pilot deployments, or collaboration, please get in touch.

Yes. We intend to support worldwide shipping.

Yes. All phantom designs are released under a CERN Open Hardware Licence, meaning the designs, drawings, and specifications are openly available to the community under a permissive, research-friendly licence.

Open source means:

• Design files and documentation are openly shared

• Methods are transparent and reproducible

• Users can inspect, validate, and adapt designs

• Community feedback helps shape future development
  

Our goal is to support open, quantitative MRI, not black-box QA tools.

Yes. The licence allows users to manufacture phantoms themselves or via third-party suppliers, provided the licence terms are respected. We also offer professionally manufactured, quality-controlled builds for users who prefer a turnkey solution.

There are many excellent commercial MRI phantoms available. The aim of Open MRI Phantoms is not to replace these, but to provide test objects the community can fully trust through open design.

By publishing complete blueprints and documentation, and supporting a community forum for collaboration, we enable transparency, reproducibility, and shared validation. Several designs directly address requirements in UK guidance, including breast fat-saturation QA and radiotherapy orientation checks.

Our phantoms are intended for research, development, and quality assurance activities within MRI services. They are not medical devices and are not used for diagnosis or direct patient care. We provide detailed documentation to support local governance, validation, and QA workflows.

Yes. Our designs are focused on quantitative metrics, including:

• Geometric distortion

• Orientation and spatial consistency

• Proton density fat fraction

• Fat Saturation efficiency

Design choices are informed by published methods and clinical relevance.

Our geometric distortion phantoms have tractability of ground truth distances documented with NIST-aligned measurement methods. As individual plates are CNC milled from acrylic, high tolerances (0.05 - 0.1mm) can be achieved, and measured per plate as part of the assembly process. This supports consistent benchmarking across scanners, sites, and timepoints.

Absolutely. We actively encourage:

• Design feedback

• Validation data

• Software tools

• Protocols and workflows
  

A community forum will provide a space to share data, software, and experience.

Yes. We have developed web-based QA analysis tools for the MammoSphere phantom, which are currently in beta testing. In parallel, we actively encourage the wider community to develop, share, and validate open analysis software alongside our phantom designs.

Our aim is to support transparent, reproducible quantitative MRI workflows through a combination of in-house tools and community-driven software.
