IEDSTP, based on standard N42.55, is a pair of test pieces designed specifically for use with IED mobile security x-ray imaging systems. IEDSTP can be used quickly and easily on a routine basis to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. Image quality is measured simply by taking defined measurements or by counting the number of details detected or resolved in the image. Recording these numbers over time will show any trend suggesting deterioration in imaging performance.
