NUCLEATION AND ACTIVATION TECHNIQUES FOR USE IN ULTRASOUND IMAGING
摘要
A method of activating an ultrasound contrast agent such that an increased number of microbubbles are produced and subsequent ultrasound images using the activated agent are enhanced. Hypobaric methods are disclosed which provide significant increases in bubble population per unit volume over unactivated solutions. The method is particularly useful for the activation of the dispersed phase in a gas or liquid in liquid emulsion.
