In fMRI it is attractive to precisely know the spatio-temporal magnetic field evolution in the imaging volume during the scan. On the one hand, such knowledge can be taken into account for image reconstruction; on the other hand, it could be a useful means of subject surveillance and of monitoring the course of a study for retrospective analysis. Recent advances in field monitoring hardware and methods actually promise to offer such capability. The present work aims to explore this proposition, using recent concurrent magnetic monitoring technology.
