Paper Abstract

Propagation-based phase contrast imaging allows low absorbing materials to be studied non-destructively using hard xrays, generating additional edge contrast through interference effects. Here we will present recent work undertaken at Manchester University's "Henry Moseley X-ray Imaging Facility" studying the applicability of lab-based phase contrast tomography to the imaging of spider specimens preserved in a range of amber types. New spider species are identified using distinctive anatomical features, including the modified structures of the anterior leg-like appendages (pedipalps) of mature males. We will describe three different strategies adopted in dealing with the phase artefacts inherent to the technique, giving a clean segmentation of important features and resulting in the classification of new species.
