The use of an image analyser for dimensional quantification in ultrasonic images

The use of a sophisticated commercially available image analyser is described in the context of obtaining numerical geometrical data from ultra-sonic visualization systems. As an example of its value, its application to the ultrasonic foetal monitoring is discussed. The main features are light pen selec¬tion, with immediate display and numerical analysis. Whereas the instrument is too sophisticated for routine use it could be invaluable in ascertaining the design specification of a simpler purpose-built system for incorporation into ultrasonic visualization equipment.
