Development of new methods to measure in vivo properties of human body tissues. This project will develop new methods of noninvasively measuring the viscoelastic properties of soft tissues in live humans, using a novel magnetic resonance elastography technique. These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo.

This project will develop new methods of noninvasively measuring the viscoelastic properties of soft tissues in live humans, using a novel magnetic resonance elastography technique. These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo. These techniques may be useful in diagnosing soft tissue disease or injury which are currently difficult to detect using standard imaging techniques. It will also explain how the muscle-tendon unit moves during normal motion in live humans.Read moreRead less

Active polymer surfaces for control of fluid movement. The realisation of a diverse array of remote or portable chemical/biological monitoring systems depends on the development of low power fluid management protocols. The use of appropriate conducting polymer surfaces should enable this to occur. We envisage the integration of these fluid management platforms into portable, remote autonomous monitoring systems for environmental industrial and biomedical applications.

MicroPET is an advanced imaging technology that measures important biochemical processes, such as enzyme activity rates and receptor binding, in the living rodent brain. However, the requirement for the animal to be anaesthetised precludes the study of behavioural changes in response to sensory or drug stimulus during the imaging study. In this research, we will develop novel motion tracking and computational algorithms that enable microPET to non-invasively image the brains of conscious, freely moving animals while simultaneously observing their behaviour. These new technologies will, for the first time, allow neuroscientists to study the genetic, behavioural and neurochemical correlates of brain disease.Read moreRead less
