Most Central New Yorkers probably picture an ultrasound machine as large unit in a dark room at a hospital or doctor's office.  Well, advances in technology have shrunk the devices to about the size of a tablet, and they're small enough to carry in the tight confines of a rescue helicopter.    Director of EMS Education at SUNY Upstate Christian Knutsen says ultrasound machines once relegated to hospitals have come a long way from the large units that radiologists struggled to read not that long ago.    EMS professionals Monday got hands-on training with the portable units on real patients.
