Mike has made some good points. I was also wondering why you had decided upon medical imaging field service work. think

Other than that, as you have already identified, to get into medical imaging tech support you really need to get some manufacturers' training under your belt.

For me, one of the appealing things about "medical equipment" in general has always been its technical diversity. So what about "general" biomed work (tech support of medical equipment); does that hold any attraction?

If so, it might be worthwhile approaching companies providing tech services to the NHS. The likes of BCAS, EBME, TBS et al. Although they will always be keen to hear from techs who can "hit the ground running" (as it were), they may also be able to accommodate someone still on the "nursery slopes" (that is, as a trainee).

Otherwise, and in any case, why not have a word with Rob* and (or) Ed.

For ultrasound, you could try MIUS.

Lastly, in order to get your foot in the door, it might be worth touching base with the well known agencies** who place techs on short-term (temporary) "bookings" - usually in hospital biomed departments. If you are really keen to learn, and are mobile (willing to work anywhere for a while; although most placements tend to be in London or the Home Counties, some also crop up in the Midlands, and in large cities like Manchester), this can be a way of gaining a fair amount of experience over a short(ish) period of time.

"Volunteer"? There's always plenty of work that needs doing in the Charity Sector! That's also a good way of proving to yourself (if nobody else) that "medical equipment" is really what you want to be involved in! whistle

* Avensys can also help you out with training. In your area, too!
