Your job will be lonely becuase you'll be handling with the
diagnostics. It just to be the doctor doing this job... but in
order to free up the doctor's time, you will be solely responsible
in providing the doctor a report of the diagnostics.
Let say if a doctor suspect the patient is having some sort of
tumour in the stomach, the doctor will send the patient to you lab.
You'll use the state-of-the-art (as they always claim) machine to
see whether the patient is having tumour anot...
You can work in the hospital's diagnostics department. It's
highly in demand now. It's the type of job where it requires
experience. The longer you work for diagnostics, the most
experience you have, the demand for your experience will be
greater.
I took a look at the course structure and thought that it is
quite comprehensive 
and practical, and you'll be able to apply what
you'll be learning in the real-life situation.
Regarding about the medical course, you will need to check with
the school itself. But based on personal opinion, i think it's not
the medical school entry course requirement they are looking for,
but you still have the advantage.
I didn't read Diagnostic Radiography~ I used to read Biomedical
Sciences.
