3D X-ray Histology Scanner

Overview

This is a custom-designed µCT scanner optimised for high throughput 3D X-ray Histology. This scanner was designed by the μ-VIS and the XRH team and built by Nikon Xtek systems Ltd. It is the cornerstone of the second phase of development of 3D X-ray Histology, which is fully funded by Wellcome Trust (2019-2022; £1.14M; Wellcome Trust, Biomedical Resource and Technology Development Grant).

The XRH scanner can be used for non-destructive radiographical and tomographical inspection of biomedically relevant specimens, and is optimised for high-throughput imaging of unstained formalin-fixed and paraffin-embedded (FFPE) soft tissue specimens.

The equipment was commissioned in January 2020, and is hosted at the Biomedical Imaging Unit at University Hospital Southampton.
