Image Quality Indicator for evaluation of Basic Spatial Resolution<\/h4>\n

The Duplex IQI is useful for many X-ray applications, especially in digital X-ray. Designed for evaluating total image unsharpness of X-ray films now it is mainly used for basic spatial resolution evaluation of digital images according to EN 13068 (Radioscopy), ISO 16371or ASTM E2445 (CR \u2013 Computed Radiography with Imaging Plates), ASTM E2446 and ASTM E2597 (characterization of CR systems and DDAs) and ASTM E2737 (Long term stability of DDAs). But also for digital radiology of welds (ISO 17636-2) and castings (EN 12681-2).
\nImage valuation with Duplex Wire Type IQI<\/strong>
\nIn radiography the wire pair with largest diameter d has to be identified, which cannot be separated visually. The radiographic film may be magnified up to 4X.
\nIn digital radiology the separation between wires (Dip) is evaluated. The wire pair with largest d, showing Dip less than 20 percent of the wire pair contrast, identifies total image unsharpness (U = 2d) and basic spatial resolution (SRb = d) of digital image.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_accordion_tab][vc_accordion_tab title=”Specification” show_icon=”yes” icon=”fas fa-angle-down”][vc_row_inner][vc_column_inner][vc_column_text css=””]Duplex IQI consists of following wire pairs: D13 – D1 to D13 , D15 – D1 to D15 , D17 HR4 – D4 to D17
\nMaterial for wires D1 to D3 is tungsten (W), for wires D4 to D17 is platinum (Pt)
\nDistance between wires of each wire pair equals exactly diameter of wires
\nWires are casted in a transparent, resistant and dimensional stable plastic
\nStandard and serial number are indelible casted and shown on each image[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
