MRI safety

Since interference-free and ultra compact electric-field probes allow measurements without any induced artifact on the magnetic field gradient generated by MRI machines, KAPTEOS solution meets the needs of electric field measurement inside any MRI machine, regardless their brand and their nominal magnetic field (1.5T, 3T, 4.7T, ...). Such measurements are of key importance to assess the compatibility of medical implants with MRI scans, and more broadly with MRI safety.


KAPTEOS has conducted many studies and manufactured numerous systems on behalf of its clients: time-resolved dosimetric measurements inside different biological media and tissues during a MRI scan, specific absorption rate (SAR) assessment in phantoms.

They use KAPTEOS technology for their R&D
