Classic high field MRI is a powerful tool in healthcare. However, it is an expensive and complex installation and it might be useful to supply a less convenient device adapted to a lot of usage not requiring high field potential. We have developed a very low field MRI working at between 1mT and 10mT. Main static field is providing by a water-cooled resistive magnet. In order to achieve an iso spatial resolution of 2mm in a reasonably short time of acquisition, we have worked on adapted sequences including compressed sensing and optimized detection with parallel acquisition.
