The Pro-NDT DuplexWireIQI D15 is a high-precision Image Quality Indicator (IQI) from Diagnomatic, specifically developed for digital X-ray applications in non-destructive testing (NDT). It is used to evaluate image quality – particularly spatial resolution and unsharpness – in digital systems such as CR (Computed Radiography) and flat panel detectors.

Key features and benefits

• Contains 15 groups of wire pair patterns (1D → 15D) that provide fine division of resolution levels and sharpness measurements.

• Material quality: Group 1D-3D is made of tungsten – high density and precision; group 4D-15D of platinum – for finer levels.

• Step interval (wire diameter and distance between wire pairs) varies from 0.032 mm to 0.800 mm, providing a wide coverage of resolution levels.

• Compact format – easy to integrate into standard disc or cassette setup. (Dimensions: 15 × 77.5-78.5 × 4 mm)

• Certified according to international standards for digital radiography: ISO 19232-5, EN 462-5, ASTM E2002-99 Duplex IQI.

Areas of application

• For quality assurance (QA) and technical control of digital X-ray systems (CR and digital radiography) where spatial resolution and image quality must be documented.

• Verification of system performance during setup, maintenance or periodic testing – especially in industrial inspection / NDT.

• Suitable for comparing system performance over time or between different devices to identify degraded resolution or increased blur.
