ABSTRACT:
Temporal variations in backscatter from an ultrasound contrast agent located in the vascular system and induced by movement of the scatterers are used to visualise the presence of contrast agent by determining areas where correlation between successive ultrasound images is poor. This low level of correlation arising from intravascular contrast agent movement permits distinction between stationary bulk tissue and moving bulk tissue since movement of the latter solid tissue scatterers is correlated.
