Physics in medical physics? Leaving medical physics?

I'm a medical physicist in training from the UK. One year away from being fully qualified. I feel like a technician. I have literal anxiety as I watch my maths and physics skills go down the drain (I try in my spare time, but my spare time is not much).

Has anyone (training or working to be a medical physicist) managed to collaborate with a university and get some nitty gritty maths/physics done? Some mathematical modelling? Solving a differential equation? And I'm not talking about "research" that involves developing more QA or (god forbid) more phantoms to scan.

If not, has anyone successfully transitioned out of medical physics? If so where did you end up? I feel the skillset is too niche it would be hard.

Sure. I'm a medical physicist and do a fair amount of research. I can't really speak to the UK. In Canada it's quite common for medical physicists to have adjunct university appointments and be involved in some level of research and teaching. It certainly can be more challenging if you're at a smaller clinic where you don't have access to many of the newer technologies though, and if you have to lead the project yourself. But there are usually opportunities if you seek them out. Normally when I go to conferences, I come back full of different ideas for projects and then inevitably get upset when I realize that I can't possibly work on all of them.

True there is a lot of routine in medical physics. I will be speaking from a nonuniversity affiliated clinical perspective in the US. I am retired so my comments may not precisely reflect the current situation. In my setting, I spent routinely 10 hrs in the clinic each day. This allowed for time to attend meetings and read journals. The situation that you put yourself in is a combination of the expectations of the administration and how you can achieve satisfaction. In the US MPs are paid well so the expectations of the administration are high and they do not typically pay one to do research although they do like to see their name on publications.

In the US only about 10% of physicists do research and mostly at/with university-affiliated departments. For theoretical projects your most precious requirement is time. As I said above one can find some time for one own endeavor, but will probably include some personal time. The question is how bad do you want it? If you can cobble together a few hours on your employer's time but are not willing to do the same on your time then it may not work. In the US besides the annual meeting of the American Association of Physicists in Medicine, we have affiliated regional medical physics organizations that meet regularly in which you can establish collegial relationships with other MPs. These meetings are usually located so most members can attend by automobile.

So what do your UK colleagues say?

If you feel you need to change your goals do it as soon as possible.

I'm sorry you feel that way such as these are so important to consistent quality procedures.

Thanks for your reply Choppy. Does the research you're involved in require mathematical modelling/calculus/ODEs/PDEs? I'm just looking to use techniques I enjoyed in undergrad. Would love any papers to look at. Even if it's just closely related research for anonymity purposes.

In the UK we are not even paid well, but neither are most jobs. Your $250k salaries are equivalent to our ~£50k. By the time you rebalance for the cost of living, it still doesn't pay off. In the UK, as a trainee, as well as integrating into the clinical workload, we are the ones left to take on all the research projects. In fact, I have to produce a big, year-long "innovation" project. The issue is we are either:

1.) "Researching" QA. Can we buy a new phantom? Can we make some code to automate this other QA?
2.) How well are we performing (audits)? Adaptive radiotherapy for example - let's pull some numbers out and see if we are doing better than we were or lets see if we can reduce PTV margins.
3.) "Assisting" medical doctors and PhD students in biomedical/neuroscience in their projects. By assisting I mean, with MRI for example, if there is a cool research project - the MRI physicist's job is to make sure it's safe, but at least their names on the paper I guess.

So after that realisation, I looked to research papers. I am specialising in MRI and radiotherapy. In MRI the big thing right now is AI and deep learning (not physics but at least it involves some maths and programming). I look at the research papers - all biomedical engineers (Medical physics doesn't give me the skillset to get involved and yes I have done courses in deep learning in my spare time to try). So I turn to radiotherapy - physicists outside of medical physics study and develop FLASH radiotherapy. So I go to conferences and I am met with 1.), 2.) and 3.). IPEM is to us what AAPM is to the US. I have quite literally been in a conference where MRI physicists argued why they even bother doing some redundant QC.

I have given my spare time to create code such as discreetly solving the LBTE vs stochastically via monte carlo to show the difference in treatment planning algorithms. It wasn't worth the extra stress of no free time. The student's don't need to know the physics that in-depth. So it was not used in the curriculum.

Yes, these things we do are all very important to a hospital. Is it physics? No. Does it involve physics? I hear the argument that understanding the fundamentals is what makes it physics - it's important when things go wrong. One could argue in the same vein that understanding the physics of washing dishes is beneficial as you understand to clean the dishes you need to create friction. Lastly, when things go wrong, it's most likely a call to the vendor these days. Not back in my manager's day so he reminds me.

I'm confused. Is this comment with regard to your training program? Did you not know all these issues before you entered this program? According to https://www.erieri.com/salary/job/medical-physicist/united-kingdom the entry-level salary for an MP is £86K ($(US)106K) for a PhD. What is your degree?

Really? About ten years ago we had a similar discussion with one who criticized the term medical physics. I think @Choppy remembers.

I was wondering, are your aspirations in theoretical physics? Most of the MPs I knew did their degree work in experimental physics. Physicist are recruited into MP because of their skills first and knowledge of physics second. Those skills include problem-solving, analytical skills, attention to detail, and understanding of physical principles and their technology application. Physicists work with physicians to acquire, site and use equipment with suitable characteristics for the task, Physicians depend on the MP to make good recommendations and to ensure that they are the best possible for the circumstances and continue to work that way. Something that entry MP may not know is that they work on a day-to-day basis with many different healthcare professionals including physicians, nurses, technologists, administrators, and even janitors (sometimes). They must have good communication skills and a great amount of flexibility. It is not a job for everybody with a PhD in physics.
