Abstract
A method for displaying a passive cavitation image that shows characteristic information of a passive cavitation includes: receiving an ultrasound signal caused by the passive cavitation; generating a plurality of first passive cavitation images for the passive cavitation at predetermined respective time frame using the received ultrasound signal by a DAS beam forming; generating a plurality of second passive cavitation images in which a maximum magnitude signal region is displayed by selecting a main lobe region having a magnitude greater than or equal to a predetermined value in the respective first passive cavitation image; generating a main lobe passive cavitation image in which a main region is displayed in the respective time frame by superimposing the plurality of the second passive cavitation images obtained for the respective time frame; and generating a passive cavitation image by displaying the main lobe passive cavitation image on a background image.
