AMRI is a research project that aims to realize a low-field magnetic resonance imaging (LF-MRI) device. The pilot application is a mobile stroke unit. The project develops not only the technology but also the product-service system, which includes diagnostics protocols of paramedics on-site of a stroke patient, interior vehicle design, and understanding and planning for its integration to healthcare. 

With the accessibility objectives stemming from the low magnetic field -- low device costs, convenience close to the patient, and safety -- the AMRI project aims to decrease the threshold of medical imaging for stroke and other use cases, potentially bringing quality healthcare for areas not served now, thus reducing inequality.

  • Stroke care would be greatly improved, since time to care can be shortened significantly through in-situ diagnostics, instead of solely at-hospital imaging. The selection of care, like thrombolysis or thrombectomy, can be done only after this assessment. Yet in most cases, early thrombolysis could significantly benefit the patient if they received a quick diagnosis. 
  • LF-MRI could be established for various other conditions, including intestinal fat accumulation, respiratory disease screening and diagnostics, and others. The technology can be made available close to the patient, whether in rural settings or bedside imaging in hospitals.


Participating Schools at Aalto University: Electrical Engineering and Arts, Design & Architecture.

The project is funded by the Future Makers funding instrument by the Jane and Aatos Erkko Foundation, and Technology Industries of Finland Centennial Foundation during 2020-2024.
