What kind of job should I get if I know medical imaging and optoelectronic information engineering?

My self is similar to yours. So I guess photoelectric information engineering must be your hobby and medical imaging must be your specialty. People only do their favorite thing, it is easy to get results, because I suggest that you, if you have the conditions, it is best to serve in a large imaging equipment company, so that the two aspects of knowledge can be combined, is not comparable to other engineers, so it is easier to get results. I personally chose to work in the hospital, amateur outside to find some maintenance work to do, but after graduation after 20 years, always feel so that both are not doing fine, and therefore to give you these suggestions, I hope to be able to help you.
