A simple approach to grey scale echography

R Railton and AJ Hall

The use of grey scale echography may be advantageous in some diagnostic situations, e.g. liver investigations. The effects on the recorded grey scale of different types of signal processing in conjunction with various settings of the brilliance control were investigated using a standard ultrasonic machine. The most satisfactory results were obtained when operating at a high baseline brilliance and modulating the display with signals proportional to the echo amplitude. A series of comparative pictures are shown to demonstrate these effects.
