Electroimaging involves measuring the electrical properties of tissues. These properties can be passive (conductivity, permittivity) or active (i.e. electrophysiological), and are obtained by combining morphological and functional information obtained by MRI with information obtained from electrophysiological signals such as the ECG. In this area, we are developing applications of these new tools to cardiac diseases, notably rhythm disorders, but also to inflammatory and chronic bowel diseases (IBD), and neurology.
