Thoughts on grad programs

So, I am finishing my undergrad (physics) this year and have several offers from graduate schools. What I am looking for is some insight as to what career appears to be better as far as job opportunities and pay.

I am equally split on which program I like more, so that has become a non-factor. All the schools are also very decent in their respective fields. So I need advice as far as these two programs:

Biomedical Engineering (imaging track) or Medical Physics (therapeutic track)!!!

Any and all opinions are welcome!!!

How hard would it be, if I chose biomedical engineering, got my PhD or MS, and decided to jump ship and go into a career in medical physics?
