The X-ray Fluorescence Microscopy (XFM) beamline at the Australian Synchrotron is host to the Maia x-ray fluorescence detector, developed by CSIRO and BNL . The Maia's large collection area and optimised photon event processing combine to achieve high sensitivity and photon count rates, enabling rapid, microscale mapping of trace metals in a variety of specimen types from biological to...

An x-ray image highlighting technique which might prove more sensitive than simple attenuation alteration, is imaging the x-ray fluorescence from specific markers. This technique is exploited to great effect on x-ray fluorescence microscopy beam lines like our XFM facility. On IMBL we would like to develop a lower resolution, but wider field of view method of reconstructing 3-D fluorescence...

Australia is a major wheat producer for the domestic and international market. Properties of wheat and its suitability for bread-making varies depending on the variety and the region where it was grown. Bread-making performance can also be significantly affected by dough additives including different salts. Previous studies have analysed dough structure using micro-CT but few have looked at...

Dual energy X-ray analysis (DEXA) uses computed tomography (CT) measurements at two photon energies to characterise the density and composition of materials. Results are expressed as the electron density (*Ne*) and fourth statistical moment (*R4*) describing the elemental composition similar to the concept of effective atomic number. The accuracy of the technique was investigated for liquid...
