Three Ishida IX-G2 Dual Energy x-ray inspection systems are providing quality control for chicken breast fillets and deboned thigh meat produced at the Haerland factory of Norway-based Nortura, an agricultural co-operative and the largest supplier of meat and eggs in Norway.

wher ordinary x-ray detection equipment obtains an image using x-rays of one energy, the IX-G2 uses rays of two different energies to produce two images. These are then compared, which helps to eliminate the background effect caused by the product itself and improves the detection of low density contaminants such as bone fragments.

At Nortura, the individual fillets emerge from the cut up to the inspection stage well separated from each other, but the G2 has been shown to be capable of picking up small fragments even in packs of overlapping fillets.
