Small portable MRI scanners developed

Published on July 8, 2008 at 10:48 PM · 3 Comments

The term "MRI scan" brings to mind the gigantic, expensive machines that are installed in hospitals. But research scientists have now developed small portable MRI scanners that perform their services in the field: for instance to examine ice cores.

Magnetic resonance imaging yields deep insights - into the atomic structure of a biomolecule, for instance, or into the tissues of a patient's body. Magnetic resonance imaging is one of the most important imaging methods used in medicine. However, MRI scanning has one major disadvantage: The machines are huge and extremely expensive, and almost impossible to transport.

The Magnetic Resonance working group at the Fraunhofer Institute for Biomedical Technology Engineering IBMT in Sankt Ingbert has made magnetic resonance imaging mobile. They collaborated with the New Zealand company Magritek to develop small portable devices. Dr. Frank Volke, head of the Magnetic Resonance working group, explains the core technology: "Instead of the large superconducting magnets that have to be cooled with liquid helium and nitrogen, extra-strong permanent magnets are installed in our devices. There is no need for cooling anymore." To make this possible, several permanent magnets are so arranged that the magnetic field lines overlap to form a homogeneous field. In this way, the developers have succeeded in developing small, less expensive, and above all portable magnetic resonance spectrometers that can even be powered by batteries.

    I am a student at Axia Campus in Phoenix and am writting a paper on portable MRI's and the benefits for cost savings and patient care. How much cheaper is the portable MRI?

      Just came across your post,question.  Ever receive a meaningful reply?
      I am very interested in the commercial aspects of portable MRIs.

      Your suggestions, comments will be appreciated.

      Kind regards,

    Are these scanners available for purchase and can I use one in such a way to scan or look at the infrastructure of a street or highway. Thanks J.warburton
