Applications for rod anode X-ray tubes

Icon-RT_small

Radiographic testing (RT)

Radiographic testing (RT) is an imaging procedure of non-destructive testing to represent differences in material. The density of a test object is mapped to an X-ray film using an X-ray source. After processing the X-ray film, differences in material and defects can be identified.

Radiographic testing is applied in all areas of industry and specified by numerous codes and standards (e.g. DIN EN ISO 17636-1:2013 on radiographic testing of welds)

Icon-CR_small

Computed radiography (CR)

Computed radiography (CR) with imaging plates is a digital imaging procedure, similar to the classical radiographic testing. Instead of X-ray film, a reusable phosphor imaging plate is used, that is read out by a scanner after exposure. The scanner generates a digital image of the radiographed object.

Computed radiography is used in all industries and is specified in numerous standards and codes (e.g. DIN EN 14784-1:2005 and ASTM E 2445:2005 on the classification of systems for industrial computed radiography).

Icon-DR_small

Digital radiography (DR)

Digital radiography (DR) is the most recent imaging procedure of industrial radiography. It applies an electronic detector to capture the radiographic image. Using digital radiography the digital image of a test object is available in real-time and can be evaluated right after the exposure.

Digital detectors provide higher dynamics than X-ray film so that exposure times can be decreased. Often the magnification technique is used. Digital radiography of welds is described in the standard DIN EN ISO 17636-2:2013.

Advantages of rod anode X-ray tubes

    • Detection of defects in areas that are difficult to access
    • Positioning of the focal spot closer to the area of interest
    • Higher resolution imaging, due to small focus
    • Single wall penetration (Higher magnification, no information overlap)
    • Support of new standards for digital radiography
