|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
