Abstract
A system and technique for detecting the presence of foreign material is presented. An ultrasound transmitter interrogates the bulk material and an array of detectors receives the off angle ultrasound scattering response of the bulk material. The presence of foreign material is determined when the off angle scattering response exceeds a predetermined threshold. The technique is especially suitable for the detection of bone in meat.
