The invention discloses a system and method for shielding an in-vivo interventional system from an external electromagnetic (EM) distortion, the system including: at least one distortion shield having multiple magnetic field sensors; a distortion model of the distorting magnetic field produced by a distorting apparatus, a generated field model modeling the magnetic field generated by a transmitter; and a processing module, configured to: receive total magnetic field values measured by corresponding various sensors; construct, based on the received total measured fields, the distortion model, the generated field model, an energy cost function of the generated field and the distortion magnetic field possibly generated by the distorting apparatus; and determine modeled parameter values of the sensors, of the generated field and of the distortion magnetic field so that the energy cost function is minimized. The distortion shield may include a surface-tracking sensor grid.
