Microbubbles are used to increase the signal levels in ultrasound. They can also be coated with molecules which bind them specifically to certain regions, such as plaques in arteries.
Peter Hoskins has had a longstanding programme of work developing techniques for investigation of blood velocities and arterial wall dynamics using ultrasound for clinical diagnosis in arterial disease.
Independent validation of measurements made using ultrasound imaging systems has been performed with particle image velocimetry (PIV) on ‘phantom’ systems. Led by Peter Hoskins.
