Physics is the fundamental science of many modern diagnostic and therapeutic medical procedures. For over 135 years physical principles have been applied in the development of technologies and methods to enhance the practice of clinical medicine with two major goals, more effective diagnostic imaging procedures and applying radiation for the treatment of diseases, especially cancer.
This continues to be a dynamic process with the evolution of technology throughout society and especially the impact of digital science, technology, and applications. Our current medical physics activities and clinical applications are built on the foundation of the research and developments by many of our medical physics pioneers that are our history and heritage.
The International Organization for Medical Physics (IOMP) in collaboration with the AAPM has an extensive project for documenting and publishing elements of this history, often by physicists who were active participants in the developments during the recent half-century. These are published at: and selected ones presented at the AAPM History Symposium.
Learning Objectives:
1. Follow the events and contributions of individuals in the development and evolution of computed tomography (CT).
2. Explore The Role of Cobalt-60 in Cancer Treatment Around the World.
3. Appreciate the contributions of Harold Johns to the medical physics profession and practice.
