Image Registration

For scanners with several imaging methods, i.e. computed tomography and X-ray projection, the data must be exactly congruent. For this purpose, a software module for so-called image registration was developed. Bildregistrierung Röntgenprojektion-CT (Smiths Detection)

ANSI standard for determining the image quality of CT baggage scanners

The standard “ANSI N42.45-2015: American National Standard for Evaluating the Image Quality of X-ray Computed Tomography (CT) Security-Screening Systems” was implemented on a baggage scanner and integrated into the system software. Test case for Site Acceptance Test SAT

Slurm Cluster

A computing cluster was set up to train detection algorithms. The cluster administration is based on slurm and ansible. The cluster is distributed over two computer rooms. Slurm has an automatic fail-over and thus increased reliability.

Training Data Server

Construction and administration of a training data server and an associated database with metadata We use BTRFS for the training data (> 100 TByte) and a Subversion repository for the metadata.
