vinovista exactly right kimble is making amatuer statements! everyday portable xrays are given in emergency rooms patient rooms and those machines are higer rads than dvis,,,honestly the comments made by some so called shareholders are astounding.....dvis will replace many of these machines as well as do in the operaing room what no machine has done before..i was in the er just 3 months ago when my mother inlaw was tken there and the guy in the next bad complained of chest pain and they rolled that portable xray in to check his chest...nobody wore radiation protection...happens everyday
