The Iseult project has unveiled the first human brain images obtained using a 11.7 teslas MRI, after almost 25 years of work. This world first was made possible thanks to the commitment of over 200 CEA employees, who believed in this extremely ambitious project from the very beginning
In the early 2000s, a Franco-German project was launched to develop ultra-high resolution imaging. One of the objectives was to build an imager whose key component was a superconducting magnet reaching 11.

The commissioning of the 11.7 T Iseult MRI in 2021 crowned almost 20 years of AOC research and development. In an article published in the journal Magnetic Resonance Materials in Physics, Biology and Medicine, Nicolas Boulant and Lionel Quettier, Iseult project leaders for the CEA's Joliot and Irfu Institutes, review the details of this commissioning.

In order for the images produced by the future MRI to be free of distortions or artifacts, the magnetic field generated by the Iseult magnet must be homogeneous to 0.5 PPM (parts per million) around the patient's brain. To meet this challenging specification, it was necessary to provision means of "shimming" the field, i.e. of correcting all the small defects that would inevitably arise from the manufacturing process.

High field magnetic resonance imaging at field strengths at or above 7 tesla appears to be one of the most promising techniques for the early detection of neurological pathologies. Currently beyond the reach of most MRI system manufacturers, this imaging technology is beset with new technological difficulties. The CEA Iseult project team (IRFU and I2BM) has now overcome one of these problems; the homogeneous excitation of atomic nuclei using parallel transmission.

The 11.75 tonne whole body Iseult magnet to be installed in the Neurospin centre in 2012 will push back the boundaries of cerebral imaging. A key step in the success of this Franco-German project is the development of the SEHT test station in which a nominal field strength of 8 teslas was successfully achieved in early October 2008
