Abstract
The invention relates to an insertion probe for sensing distributed temperature comprising a tube containing at least one optical fiber being inscribed with at least one Bragg grating, the tube being sealed at its distal end. The probe is characterized in that it consists of materials having low magnetic susceptibility. The invention also relates to the use of such a probe in cryosurgery to allow the use of magnetic resonance imaging.
