The field of X-ray tomography in particular is seeing rapid advancements. A series of software correction methods are now available, so that sufficiently precise CT measurements are usually possible without Autocorrection.  With Auto correction, the measurement process is even suitable for holes in motor vehicle fuel injectors with tolerances of 5 µm.  One example of the many new developments in recent years is the Werth Multi-ROI CT (ROI – Region of Interest), which enables high-resolution measurements of any desired partial region of the work piece by Eccentric tomography.  With this method, the 3D point cloud of the work piece from a low resolution overview measurement is merged with high resolution measurements of the regions interest.
