Dedication

To Dad – who practiced radiology for 50 years. I love it as much as you did.

To Mom – an educator who taught me not to care what other people think of me and my work which has held me in good stead as my work has faced resistance from the status quo.

To my wife – who has been a great mentor and to my sons – thanks for understanding the time and energy I have invested into all this during our time together.
