ISO 19232-5, EN 462 & ASTM E-2002 Duplex IQI Duplex Wire Type IQI - Total Image Unsharpness Gauge​

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.

Model Specifications
Duplex IQI - D13 (11 00155) - Standard Resolution Version

• The D13 consists of 13 wire pairs from 1D with a wire Ø of 0.80mm to 13D with a wire Ø of 0.50mm.
• Wires 1D - 3D are made of tungsten and wires 4D to 13D are made of platinum.
• Dimensions: 70 x 15 x 4 mm

Duplex IQI - D15 (11 00160) - High Resolution Version
The D15 has same wire pairs as the D13 + additional wires with diameters of:

• D15 - 0.032mm (15,625 lp/mm)

Dimensions of the D15 are 78.5 x 15 x 4 mm compared to 70 x 15 x 4 mm (standard duplex) and distance between D13 and D14 is higher to avoid mix-ups.
