Lecture: Filtered back-projection tomography part 2: And now for the equations!

Abstract
In the previous talk, I introduced the main concepts behind the most commonly-used CT reconstruction algorithm known as "Filtered back-projection" using an intuitive approach with visual examples and animations.  In this follow-up talk, I will cover more of the mathematical detail, including an introduction to some sources of artefacts in reconstructed images.

Dr Stephen Bosi obtained his PhD in condensed matter physics (studying high temperature superconductors) at the University of New South Wales. He worked for a decade in the application of optical and electronic materials to sustainable energy technology at the University of Technology Sydney, Dyesol Pty Ltd, ANSTO and the University of Sydney (where he also lectured in physics). He then conducted five years of research in medical physics at USyd and at the Prince of Wales Hospital (PoWH) Randwick, especially in the field of 3-dimensional gel radiation dosimetry. He also allowed himself to be distracted from academia by being lead author of the high school physics textbook series, "In2 Physics" (Pearson Australia).
In September he will undergo a first-order phase transition, from Research Medical Physicist at PoWH, to Lecturer in Physics at the University of New England, Armidale.
