Affordable and Low Field MRI

MRI scanners are very expensive machines that cost about 1M€/T, and a typical MRI scanner has a static magnetic field of 3 to 7T. Because of this many people in the world have no access to it. LUMC and TU Delft have worked together to develop an affordable MRI scanner. The project was made open source so it’s even possible to build your own, and quite a few copies have been built around the world.

The main way the costs were lowered is by using permanent magnets for the main field and use cheap computing power to compensate for that. The magnet was designed at the LUMC and the mathematics and gradient coils at TU Delft EWI.

DEMO has designed and built a RF Power Amplifier, Gradient Amplifier, Low Noise Amplifier, Software Defined Radio and a Halbach Magnet.
