Ultrasonic Projection

“…Due to the possibility of obtaining images in pseudoreal time, the device using this method was named the ultrasonic transmission camera (UTC) (Ermert et al, 2000). Only some centres in the world work on this issue and there are a low number of laboratory research setups, which enable pseudo-real time visualisation of biological structures using UTC: Stanford Research Institute in USA (Green et al, 1974;Green et al, 1976), Gesellschaft für Strahlen-und Umweltforschung at Neuherberg in Germany (Brettel et al, 1981;Brettel et al, 1987), Siemens Corporate Technology in Germany (Ermert et al, 2000;Granz & Oppelt, 1987;Keitmann et al, 2002), Wroclaw University of Technology in Poland (Opielinski & Gudra, 2000;Opielinski & Gudra, 2005, Opielinski et al, 2010a, 2010b, University of California in San Diego and University of Washington Medical Center in Seattle (Lehmann et al, 1999). In most of studies, the projection parameter is the signal amplitude, not its transition time, which seems to more attractive due to the simplicity and precision of measurements.…”
