Document Type and Number:
Japanese Patent JPH11513282
Kind Code:
A
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 visualize the presence of contrast agent by determining areas where correlation between successive ultrasound images is poor. This low level of correlation 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.
