Traditional X-ray systems detect foreign objects by analyzing dark and light areas in transparent x-ray images. However, when products are overlapping, distinguishing dark areas from foreign objects becomes unreliable resulting in missed detections and false rejects.
New Ishida IX-G2 X-ray inspection systems solve this problem by using a unique dual energy process that compares absorption of x-rays on two levels. Based on medical X-ray absorptiometry, Ishida’s technology improves detection of low density pieces of metal, glass, plastic, and other foreign objects, even in overlapped products.
