COLOR ULTRASOUND IMAGING OF BLOOD-FLOW AND TISSUE MOTION

Recent years have seen the introduction of a high quality imaging moda lity which uses the Doppler shift for the study of blood flow and tiss ue motion. Colour ultrasound technology has now reached a level of mat urity and it is, therefore, timely to review its features and consider how colour techniques may develop. This review concentrates on autoco rrelator based colour systems. Recent developments are described inclu ding colour vector Doppler, contrast agents, 3D display, tissue vascul arity assessment and volume flow measurement.
