Medical Physics: Masters or PhD?? I am currently a Nuclear Engineering Masters student planning to graduate in May 2013. I am now applying to both Masters and PhD Medical Physics programs, however I am not exactly sure which route to take. Is it worth going for the PhD if I plan to do clinical work in hospitals? Prestigious schools, such as Columbia and UPenn, only have Masters programs which makes me question the necessity of a PhD if you do not plan on doing research all your life. Also, could someone in the field also explain the demand for/responsibilities of the different specialties (i.e. nuclear medicine, diagnostic imaging, radiation oncology, medical health physics)? Thanks a bunch!
