CT visualisation software
28/07/2026
North Star Imaging Inc (NSI), an Illinois Tool Works (ITW) company and industry leader in industrial X-ray and computed tomography (CT) systems, has announced the launch and availability of its efX Software Version 3.0. The release represents the most significant upgrade to NSI's proprietary software suite to date, delivering a completely reimagined efX-CT experience alongside user interface enhancements across the entire efX product family.
efX 3.0 was designed to address the evolving needs of quality engineers, inspection technicians and research professionals operating in some of the world's most demanding industries, including aerospace, automotive, medical devices, electronics, defence and additive manufacturing. The new version focuses on streamlining workflows, improving collaboration and giving operators the tools they need to analyse complex datasets with greater speed and precision.
At the core of efX 3.0 is a next-generation efX-CT module built around a project-based architecture. Users can now save their entire working state, including volumes, clipping objects, annotations and bookmarks, into a single NSIX project file. This makes it easy to resume work, share findings and maintain consistency with colleagues and customers.
The new efX interface features a unified docking and layout system that consolidates all views into a single, customisable window. Operators can dock, undock and rearrange panels to match their preferred workflow, pop out views for multi-monitor configurations and save layout presets for repeated use. High-resolution volume animations give teams the ability to produce rendered videos and image sequences without manual manipulation, achieving higher frame rates and quality than real-time screen recordings. Animation workflows can be saved and reused across different volumes, streamlining reporting and presentation tasks. Multi-volume support allows users to load and register multiple datasets within a single efX-CT session, enabling direct side-by-side comparison of parts.
The new 2D and 3D annotation tools let operators place voxel-level markers that are visible across both viewing modes and can be paired with bookmarks to document areas of interest. Additionally, preview surfaces provide operators with a quick surface estimation before committing to a full computation, saving valuable processing time.
With support for the ASTM E1695 standard, efX 3.0 is an important milestone for customers operating in regulated industries that require standardised CT inspection procedures.
