I would say a moderate amount of physics and only minimal mathematics outside of some specialized areas. So for example, everyone working with X-rays, technologists and radiologists, must understand the basics of atomic physics, types and characteristics of radiation and radiation safety. Radiologists go on to have more extensive training including radiation safety and human effects of radiation, how each modality functions to produce or make use of radiation, shielding, contrast agents, and the information systems used, etc. The physics is very focused on those topics directly related to clinical use of radiation with more theoretical aspects left to researchers.

I can’t recall an event that required calculus in a typical clinical setting. Again, researchers in modalities or image processing or deep learning would go into much more advanced mathematics. Not a nurse or doctor, but a Radiologic Technologist, for 30 years. One thing that really burns up an X-ray tech is nurses in the ER that order x-rays and who don’t know WHAT to order, so they order waaay too much. Most of us normally simply refuse to do the entire battery, letting the doctor see the patient first, and he/she usually cancels most of the unnecessary exams. I have watched doctors cancel thousands of unnecessary nurse-ordered exams over the years.
