Casting parts have complicated internal structures that requires non-destructive testing techniques to detect defects. Industrial CT X-ray inspection is one of the most important way of non-destructive testing techniques that are used to identify defects. Due to the material composition of the casting parts being mostly iron, aluminum or zinc and other metals, relatively high energy x-ray needs to be incorporated in the industrial CT inspection systems. X-Scan Imaging Corporation provides detector systems that are radiation-hardened and perform well under high energy x-ray doses.
