Overview
The Duplex IQI is used in many X-ray applications. It is especially made for digital X-ray applications in order to evaluate image unsharpness (film and digital images) and basic spatial resolution in digital images according to EN 13068 (Radioscopy), EN 14784 and ISO 13671 (CR - Computed Radiography with imaging plates), ISO 17636-2 (digital radiography of welds - flat panel detectors) or ASTM E 2597 (characterization of digital detector arrays). A new ISO is in the works, describing the possibility of using the Duplex IQI for the determination of focal spot sizes on X-ray tubes.
