Abstract

Ultrasound has been used in diagnostic medicine for nearly 30 years and scanners have been commercially available since the mid 1960s. The first generation of bi-stable scanners displayed the twodimensional scan information on a cathode ray tube as a series of bright dots where only echoes above a certain threshold were displayed. These corresponded to relatively large reflecting surfaces within the body, such as the capsule of the liver, the portal vein or the great vessels. In modern scanners a grey-scale display is now standard whereby each echo signal amplitude is related to a shade or level of grey, the stronger echoes delineated by the more reflective surfaces, thus giving information on the appearances of soft tissue parenchyma which was not available previously with bi-stable equipment. Real-time ultrasound units which we consider suitable for intensive care scanning are of two basic types; either mechanical sector or multiple transducer systems.
