Who established that the DViS is a low radiation emitting device? For what quality of images? Don't tell me that Dean said so. The FDA will never accept data on radiation as fact without beta testing. IMGG can't do beta testing until they can produce high quality images one after the other. No high quality images means no beta testing means no FDA approval. We may not be receiving high quality images from Dean because the radiation dose to produce them may be too high. There is something that is wrong here and to continually blame the FDA is a mistake.
