CONTRAST AGENT MANIPULATION WITH MEDICAL ULTRASOUND IMAGING

摘要

Contrast agents are manipulated (42) with acoustic radiation force while ultrasound imaging. Continuous waves for acoustic radiation force are transmitted (42). Substantially simultaneously, pulsed waves for imaging are transmitted (44). Low mechanical index continuous and pulsed waves may be used to increase binding efficiency of drug containing contrast agents with the tissue for treatment. Various techniques may be used to minimize (46) the effect of the continuous waves on imaging (48) with the pulsed waves. The acoustic radiation force may be transmitted (42) with an amplitude profile and/or unfocused or defocused.
