Systems and methods for detecting contraband using quadrupole resonance and X-ray detection

摘要

A contraband detection system is provided. The contraband detection system includes an X-ray system including a front X-ray transmitter/detector and a rear X-ray transmitter/detector. The contraband detection system further includes a quadrupole resonance (QR) system comprising a first QR coil, and a second QR coil, wherein the first and second QR coils are located between the front and rear X-ray transmitter/detectors, and wherein the first and second QR coils are constructed from a material having a low mass attenuation coefficient and a high conductivity such that the first and second QR coils do not substantially interfere with transmitting X-rays and detecting emitted photons using the X-ray system. The contraband detection system further comprise a computing device coupled to the X-ray system and the QR system, the computing device configured to detect contraband based on signals received from the X-ray system and the QR system.

1. A contraband detection system comprising:
an X-ray system comprising:
a front X-ray transmitter/detector;a rear X-ray transmitter/detector, wherein said front and rear X-ray transmitter/detectors are each configured to at least one of transmit X-rays and detect emitted photons to generate at least one image of a subject standing in a subject region; a quadrupole resonance (QR) system comprising:
a first QR coil; anda second QR coil, wherein said first and second QR coils are located between said front and rear X-ray transmitter/detectors, and wherein said first and second QR coils are constructed from a material having a low mass attenuation coefficient and a high conductivity such that said first and second QR coils do not substantially interfere with transmitting X-rays and detecting emitted photons using said X-ray system; and a computing device coupled to said X-ray system and said QR system, said computing device configured to detect contraband at the subject region based on signals received from said X-ray system and said QR system.
