Abstract
Analysis of random samples as well as inspection and verification of prototypes, e.g. in aluminium casting industry, demand fast non-destructive testing methods with high geometrical resolution and 3D imaging capability. X-ray computed tomography (CT) is specially suited to this and reached increasing importance due to the fast development of system components and software during the last few years.
A complete examination of an object with two-dimensional computed tomography (2D-CT) is very time consuming because all object slices have to be measured one after each other. In contrast to this the three-dimensional computed tomography (3D-CT) is able to examine a complete object volume with one single scan. A flat, two-dimensional detector is used and the object has to be rotated only once, resulting in short examination times. In addition to that big efforts have been made to accelerate the reconstruction algorithms by optimization and parallelisation.
Due to the different demands of several applications in industry a modular software was developed, which includes various system components as manipulation system, x-ray tube (450 kV, 225 kV mini focus and micro focus tubes) and detectors.
We describe this concept of an industrial 3D-CT system family, with short measuring and reconstructing times. The capability of such systems is demonstrated by several examples.
