IBSim-4i and the gVXR User Meeting come together in a unique, collocated event that bridges innovation in simulation and imaging. Together, these events create a dynamic environment where theory meets practice, fostering exchange between communities working at the forefront of computational imaging. By aligning these two communities under one programme, the event offers attendees a richer experience with cross-cutting sessions, shared discussions, and networking opportunities that spark new collaborations. Participants will benefit from exposure to cutting-edge research, hands-on insights, and emerging tools that are driving progress in areas such as industrial inspection, material science, manufacturing, healthcare, and digital twins. Whether you are an established expert or an early-career researcher, the joint IBSim-4i and gVXR User Meeting provides an inclusive and forward-looking platform to connect, learn, and contribute to the evolving landscape of simulation-driven discovery.

About IBSim-4i

Image-based meshing is the process by which 3D images (e.g. X-ray CT or laser scanning) are converted into ultra-high resolution simulations. 3D imaging is increasingly being used in the industrial sector for inspection, non-destructive testing / evaluation (NDT/NDE) and metrology but image-based simulation is still an underutilised technique. IBSim-4i is a 4-day programme consisting of a 2-day training course followed by a 2-day users' forum. Our aim is that the activities of IBSim-4i will facilitate a wider adoption of image-based simulation and provide a platform to discuss the cutting-edge developments in the field.

About gVXR

gVXR is an open-source framework to simulate X-ray images in realtime on the graphics processor unit (GPU). Software developers and scientists can use gVXR with a wide range of programming languages. Its accuracy has been benchmarked with state-of-the-art Monte Carlo simulations and experimental data paving the way for digital twining of clinical and industrial devices. It has been used in a wide range of applications in different scientific fields (see https://doi.org/10.1016/j.nimb.2025.165804 for a recent review).

The User Meeting provides a dedicated space for users and developers of the gVirtualXRay platform to share experiences, showcase applications, and shape the future of fast, physically accurate X-ray simulation.

Organised by the Applied Mechanics Group and the Materials and Characterisation Group
