G'day from a down-under Mac user!

I was introduced to this subject in 1972 by Jim Malone, PhD while studying at the College of Technology, Kevin St, Dublin, Ireland. I was doing the third year of a diploma course in applied physics. Some years later I was lecturing in the same course and adapted Jim's notes for my lectures. I was also working at this time as a physicist in nuclear medicine at the nearby Meath Hospital. I further adapted the notes for lectures within a physics degree course at Kevin Street. And later still for a medical radiations degree course at RMIT, Melbourne, Australia. As such the notes benefitted considerably on the basis of questions from students as well as comments from clinical and academic colleagues. By 1997 I was using the notes on a visiting professorship at Kuwait University. Whilst there I was inspired out of boredom to formalise the notes into a textbook. I subsequently developed the book into a set of webpages which lay dormant on a cd-rom for five years or more. Until mid-2006, when I uploaded them to wikibooks.....
I started giving lectures in this subject area whilst working in Melbourne in the late 1980s, although I'd been doing research using digital radiography for some years previously, and these lectures still continue to this day (2013) at the University of Melbourne. The concept for the wikibook arose out of this experience as an attempt to reformulate and modernise topic presentation. The material draws heavily from Heggie JCP, Liddell NA & Maher KP, 2001, 4th Edition and from discussions with colleagues at St Vincent's Hospital Melbourne. The wikibook could be extended to include mammography and MDCT physics in the future.

I'm interested in learning about the WikiBooks phenomenon by engaging with it and exploring its potential for the continuous evolution of instructional resources.
