Patent ID: 8766634

Claim:
A device of estimating a dose of ionizing radiation absorbed in an intra bone volume, comprising: a static magnetic field source adapted to generate a substantially static magnetic field in a probing space having a volume of less than 2 cubic millimeter (mm 3 ), said probing space being placed in front of a distal end of static magnetic field source, said static magnetic field source being sized and shaped to maneuver said probing space to overlap with an intra bone volume of said bone; a micro resonator mounted in adjacent to said distal end; and at least one transmission line which feeds said resonator so as to generate a microwave magnetic field at said probing space, wherein said micro resonator acquires, from said probing space, a signal returned from to said generated microwave magnetic field and indicative of radiation induced paramagnetic defects in said probing space so as to allow a spectrometer to compute a dose of ionizing radiation absorbed in a portion of a bone placed in said probing space according to an analysis of said signal.
