I have a few questions about Medical Physics that I am hoping someone can answer. Any responses would be greatly appreciated. 1. What is the difference between the four subfields of Medical Physics: Therapeutic Medical Physics, Diagnostic Medical Physics, Nuclear Medical Physics, and Medical Health Physics? 2. Do you apply and enter a residency in one of the four subfields and then can only have a job in that one specific area or can you enter a residency regardless of which area it is and have a job in any of the four areas? 3. What is the difference between a DMP and a PhD in Medical Physics? 4. Also, I wanted to point out that I recently got interested in Medical Physics from having conversations with my older brother who is finishing his Master of Science in Medical Physics. He is getting his Master of Science in Medical Physics online from some international school in Europe (I don't know the name of it) and originally wanted to move to Germany after he finished the program, but now he recently changed his mind and wants to stay in the U.S. after he finishes it up. What would he have to do now because his international school isn't apart of the CAMPEP if he wants to get a residency in the U.S. for Medical Physics after he finishes his program? If I do intend to enter a graduate Medical Physics program later on I am definitely entering one that is apart of the CAMPEP so I don't have any complications. Thank you for taking the time to answer my questions.
