We had a couple of Ultrasound scanners in for evaluation the other week. One company stated that there was no annual service requirement for their scanner, only user QA tests. Their repair policy was that they would swap out faulty kit and guarantee next day delivery. they didn't mention whether or not the swap was permanent or a loaner. So a possible future for biomeds might be as van drivers!
Both scanners had remote intrrogation capabilities, i.e. could fault find/ service over the 'net. I think to keep in the game as it were we will need to be more IT savvy.
