Project's goal

To present the “RadalyX” technology of Radalytica for advanced quality control using a robotic computed tomography scanner equipped with photon-counting X-ray imaging detectors.

Results

A technical presentation and live demonstration of the RadalyX system for X-ray non-destructive testing based on flexible robotic CT. Introduction to the properties of photon-counting technology for X-ray imaging. Exploration of the technology’s potential for quality control – particularly for light alloys, hard-to-image defects, and giga-casting methods.

Solution description

As part of scouting new technologies, Škoda FabLab facilitated a presentation at the Prague premises of Radalytica, attended by a total of 26 employees from the areas of Car Production, Component Production, Quality Management, and Brand Management. The presentation introduced the principles of the RadalyX mobile multimodal robotic system. This non-destructive testing system typically consists of two synchronized collaborative robotic arms, on which an X-ray source (50 – 220 kV) and an advanced photon-counting X-ray imaging detector manufactured by the Czech company ADVACAM are mounted.


Unlike conventional CT, the robotic arms are not limited by the tunnel size and can gradually scan the entire sample from the outside. The company also demonstrated the tomosynthesis method, which allows an X-ray image to be focused at a specific depth within the sample, and backscattering, i.e., generating an X-ray scan from the backward scattered of reflected X-ray photons (in practice, this allows both the X-ray tube and detector to be placed on the same side of the sample).

The photon-counting technology is based on digital processing of each individual photon that strikes the sensor surface, directly in the readout electronics located under each pixel of the detector (pixel size: 55 μm). According to the data presented, this approach achieves a practically unlimited dynamic range, enabling simultaneous imaging of materials with both high and very low density in a single shot.

During the theoretical lecture and practical demonstration in Radalytica’s laboratory, the solution was presented as particularly suitable for scanning large components cast in a single piece using giga-casting, with results from previous scans shown. Other potential applications include weld inspection, composite inspection, foreign object detection, delamination detection, and battery analysis.
In addition to X-ray imaging, this robotic system can also integrate other imaging and inspection modalities, including ultrasound, laser profiling, and acoustic laser systems.
