Abstract
The present invention relates to a device for detecting a non-authorized material in a zone with protected access, the device being characterized by the fact that it comprises in combination: a supporting base (100) designed to receive a single foot wearing a shoe, of an individual to be inspected; detector means (430, 450, 460) adapted to detect a target material by employing at least one magnetic resonance technique to detect said non-authorized material and associated with the support base (100); and position-identifying means (400) on the support base (100) suitable for imposing accurate positioning of the foot of the individual being inspected relative to the detector means.
Claims24
A device for detecting at least a non-authorized material in a zone with protected access, the device being characterized by the fact that it comprises in combination:
- a supporting base (100) designed to receive a single foot wearing a shoe, of an individual to be inspected;
- detector means (430, 450, 460) adapted to detect a target material by employing at least one magnetic resonance technique to detect said non-authorized material and associated with the support base (100);
- and
- position-identifying means (400) on the support base (100) suitable for imposing accurate positioning of the foot shoe of the individual being inspected relative to the detector means.
A device according to 8, characterized by the fact that the Helmholtz coils (450, 460) are equals (symmetric) and connected in series, in order to be supplied exactly with the same current.
A device according to 8, characterized by the fact that the detector means comprise additional RF coils, properly shaped, surrounding the ankle and calf area of the individual being inspected, said additional RF coils being outside of the uniform static magnetic field generated by the Helmholtz coils and, therefore, being used for the substance detection based on Nuclear Quadrupole Resonance.
A device according to 12, characterized by the fact that the RF shoe-TX/RX antenna (430) is a high-Q inductor.
