I specifically learn called biomedical engineering, our school this specialty is the direction of the medical testing equipment.
1. Professional courses are, physiology, biochemistry, anatomy, signal processing, digital signal processing, biomedical signal processing, biomedical electronics, engineering optics ... and so on. And so on.
These very useful a, the current test instrument to the majority of optical and electronic means for the means of testing, so to learn engineering optics. Then how to test out the results? To learn signal processing. For human medical stuff, natural science to anatomy and other things, production and maintenance of electronic equipment must be able to master electronic technology, so to learn analog, digital, electronic technology.
2. If you go to graduate school, you can just apply directly to the school you want to go to. What schools have this specialty? You mean medical electronic instrumentation and maintenance, right? This I do not know, because my major is called biomedical engineering, but by some schools in the biomedical engineering program is not medical instrumentation direction. So you need to consult before applying.
3. Why can't you fix it? These instruments teachers have dismantled and installed many times .... The teacher is not good enough to ask for money to repair it?
4. How is it possible to do business without start-up capital?
5. You can go to the laboratory to do equipment maintenance work, just fierce competition. After all, other work in the hospital medical school is not enough.
I hope to solve your problem.
