For decades, manufacturers have struggled with the integration of Traditional Machine Vision. Visual Quality Assurance (QA), gating and sorting has always been the necessary evil, helping manufacturers reduce the risk of defective products. The process begins with the manufacturer identifying a need for QA and assessing whether a certain point on the production line is worth the time, effort and cost of implementing a machine vision solution.

 Procedures should be explained and performance evaluated according to an objective, predefined measurement system.  

 X-ray systems detect foreign objects by measuring the density of product and detecting differences or irregularities.
