For many years, Fraunhofer IZFP’s CT-Automat, a system for computed tomography (CT), has proven to be a fully automated laboratory system for industrial quality control. Several leading European seed companies are using it as an effective tool for control and quality assessment in seed production for fast obtainment of objective quality statements concerning single seeds. This nondestructive inspection procedure evaluates the quality of the seed without damaging the seed itself and without altering the surface.

The CT Automat is used by Europe's leading seed producers to minimize seed rejects especially in case of sugar beet seeds to ensure at same time high-quality seeds, a “guaranteed germination rate", and a steady.

This fully automated CT system was developed under the direction of Dr. Felix Porsch, group leader "3D X-ray CT" at Fraunhofer IZFP in Saarbrücken, Germany. "Compared to conventional radiography, computed tomography can provide much more detailed and especially quantitative information, as it provides the full volume information of each individual seed", Dr. Porsch explains, whose team of scientists and engineers has adjusted this inspection method for use in seed production and then qualified it for industrial use in joint collaboration with industry partners as a nondestructive and fully automated inspection system that can be integrated into the quality control of virtually any manufacturing process of small parts. "Our CT-Automat and its corresponding automatic image analysis software provide an easy way to considerably raise both, the number of random samplings and the reliability of the analysis results. As a consequence, the quality of the seeds has undergone a significant enhancement," Dr. Porsch emphasized further.

But the scope of this "All-rounder" is not restricted to the evaluation of seed: A whole bunch of applications become accessible, e.g. the characterization of material samples (pore or particle size distribution) or bulk goods, or the integrity control of components. This is true even for single parts within a large batch of small parts. In particular, samples of synthetic, organic or ceramic materials and light alloy are suited for tests with the X-ray machine. "Our automated CT system provides the opportunity to examine a large number of samples or components in a short time. Thus, the system
