Can I refinance from an FHA loan to a Physician Loan?

I purchased a home last year using an FHA loan with 3.5% down. I qualify for a Physician loan but chose the FHA loan instead due to some credits I was offered and a better interest rate.

I am interested in refinancing to remove the mortgage insurance. Can I refinance to a Physician Mortgage, or would I be better off waiting until I have enough equity to refinance to a traditional loan without PMI?
