Enhanced Motion Visualisation and Characterisation in Ultrasound Imaging: Work in Progress

At the moment ultrasound technology is not capable of delivering the necessary visual and quantitative information required by many medical applications where motion study is required. Doppler ultrasound iS sensitive only to relatively high velocity components of motion and users must themselves interpret the gray level image to determine any useful properties relating to the remaining large range of lower velocity components. Characterisation of motion for slow phenomena over elapsed time periods of the order of minutes is especially difficult for humans to perform.
