Abstract:
1. A susceptometer for non-invasive iron level measurement in a body comprising: a first heat insulating case comprising a support structure, the first case being made of a non-magnetic and essentially insulating material; an alternating magnetic field source generating a magnetic field within the first case, the source being supported by the structure; a first and a second magnetic field sensors supported by the structure and disposed on opposite sides of the source, a first screening region being interposed between the source and the first sensor and a second screening region being interposed between the source and the second sensor, the temperature within the first and the second screening regions being controlled by limiting variations of the temperature to a predetermined maximum value; means for disposing the body within the first or the second screening region; and means for processing electric signals perceived by the first or second sensors, the signals being indicative of a variation in the magnetic field caused by the body in the first or second screening regions.
