Industrial CT software solution

29/04/2025

Nikon Metrology NV (Nikon Metrology), a subsidiary of Nikon Corporation (Nikon), has announced the launch of Scatter Correction CT, a software solution designed to address the challenges posed by X-ray scatter artefacts in industrial computed tomography (CT) scanning. By employing advanced physics-based modelling techniques, Scatter Correction CT significantly improves image clarity and measurement accuracy, particularly for dense materials such as aluminium, steel, ceramic and Inconel.

X-ray scatter artefacts have long been a significant issue for CT scan operators, hindering their ability to obtain clear images of internal and external structures. X-rays, as with visible light, typically travel in straight lines but are sometimes absorbed and re-emitted, which can change the direction of travel. This issue can manifest as cloudy halos surrounding high-density regions, false inhomogeneities within homogeneous regions and edge blurring across material boundaries. Scatter Correction CT effectively simulates and corrects for these complex interactions, removing the detrimental effects of scatter.

By correcting for X-ray scatter artefacts, Scatter Correction CT dramatically improves image quality, enabling more precise visualisation of internal and external structures, defects and fine details, and it allows for more precise and reliable measurements of component geometries and internal features, critical for quality control and Industry 4.0 manufacturing.

Scan times are more than 100 times faster than traditional scatter-free 2D CT methods, it is claimed, allowing manufacturers to significantly improve throughput and accelerate product development.

Scatter Correction CT is available across all Nikon X-ray sources and systems in the 225 kV and above range and is fully compatible with all Nikon CT scanning acquisition modes, providing a versatile solution for diverse industrial applications.

The correction is seamlessly integrated into the scanning workflow, requiring only a single click to enable it. This reduces the need for specialised skills and improves overall productivity.

Scatter Correction CT substantially benefits various industries, including aerospace, automotive, additive manufacturing and castings.
