Biological specimens typically combine multiple materials and structures organized in a 3D hierarchy of spatial scales. Large inter-individual variations are often present, requiring extensive sampling for statistical validity, and in some cases tissues or even entire organisms must remain alive or undamaged by x-radiation. Understanding of biological tissues has been revolutionized by 3D, noninvasive imaging provided by Computed Tomography (CT), microCT and nanoCT. Given the different spatial scales and tissue types, an enormous range of approaches are required, and the task here is to highlight how very different specimens have been and will continue to be studied by various x-ray tomographic modalities.

Topic: tomography in biology Stuart received his MSc in materials science and engineering at Northwestern University and his PhD in metallurgical engineering at University of Illinois. He was on the materials science faculty at Georgia Tech for 16 years where he became a professor. He then returned to Northwestern Uni as a research professor in the medical school. He has used X-ray diffraction for material characterisation for nearly 40 years and revised Cullity's classic text: Elements of X-ray diffraction. He has employed X-ray imaging for the same length of time, travelling to the Advanced Photon Source for synchrotron radiation 6 or more times per year for the past 35 years. He has published results of microCT studies of inorganic materials and composites and of mineralised tissues in mammals and echinoderms for the 30 years. He has over 240 publications, was the conference chair of the SPIE conference "Developments in X-ray tomography" from 2005 until 2015, and has written the book: "MicroComputed Tomography: Methodology and Applications"
