We are delighted to announce that the 4th Imaging with Radiation conference (IMGRAD-4) will be held this year after delays last year!! The conference will be on 4-5 August 2021. Should you wish to participate, please submit your abstract and/or registration by 15 July 2021 - registration is free.

Don't miss out on this exciting opportunity to share your work and connect with others in South Africa in the broad area of radiography and tomography of materials and structures.

Did you know: the non-destructive nature of X-ray computed tomography (CT) allows examining delicate samples that can't be easily sectioned, like priceless museum artefacts, unique biological specimens, brittle engineering materials, even such things as frozen ice cream.

X-ray micro-tomographic data of live larvae of the beetle Cacosceles newmannii

Quantifying insect respiratory structures and their variation has remained challenging due to their microscopic size. Here we measure insect tracheal volume using X-ray micro-tomography (µCT) scanning (at 15 µm resolution) on living, sedated larvae of the cerambycid beetle Cacosceles newmannii across a range of body sizes. In this paper we provide the full volumetric data and 3D models for 12 scans, providing novel data on repeatability of imaging analyses and structural tracheal trait differences provided by different image segmentation methods. The volume data is provided here with segmented tracheal regions as 3D models.
