Die industrielle Computertomographie (CT) ist aufgrund der Möglichkeit sowohl außen- als auch innenliegende Strukturen zerstörungsfrei zu untersuchen für die Qualitätssicherung komplexer Baugruppen geeignet. Höhere Anforderungen an Produkte verlangen innovative Prüfverfahren. Der Beitrag stellt ein Verfahren zur temperaturvariablen CT vor, basierend auf einer temperier- und durchstrahlungsfähigen Prüfkammer mit integrierter formflexibler Aufnahmevorrichtung.   Industrial computed tomography is suitable for the quality assurance of complex assemblies as it enables the non-destructive testing of both external and internal structures. Higher demands on products require innovative testing methods. The article presents a method for temperature-variable computed tomography, using a temperature-controlled and radiolucent test chamber including a form-flexible clamping device.

An imaging system of ultrasonic detection is presented for non-destructive testing (NDT) of complex structures by using virtual instrument technology. The control devices for C-scan as well as for imaging system are designed and manufactured. In the coarse scan mode with the scan step of 1 mm, the system can quickly give an image display of a cross section of 80 mm (L) ×60 mm (D) by one measurement. In the refined scan model, the system can show a refine image of the coin. All experiments on coin, bulk metal, and other forms of specimen verify the efficiency of the proposed method. The experimental results are accurate and reliable.
