Look, I'm a proud physicist, and it prides me to know that discoveries in my field have essentially defined generations, from the unification of EM with light to the transistor, physics has at a fundamental role in advancement of both technology and understanding of the world since forever. Still, a general description of how these technologies work should be enough for people who are not going into technical roles (like being the physician specifically uses the PET, etc), it probably not even need be quantitative. I feel like we focus far too much on the details instead of relevant results in our classes. For example, calculating the net force on an object to determine it's acceleration (Newton's second law) is vital for any physicist to understand. For a biologist? Not so much. Especially when the treatment of physics gets technically complicated (like you need to consider drag forces or something), the content becomes more tedium than learning especially for students who do not plan to go into that field.
