Method and device for displaying passive cavitation image

A device for displaying a passive cavitation image that shows characteristic information of a passive cavitation, comprising:

• an ultrasound transducer that is configured to be able to generate ultrasound to a ultrasound transmitting medium;
• a pulser power supply that generates a pulse power applied to the ultrasound transducer;
• an imaging probe that receives an ultrasound signal caused by a passive cavitation generated by the ultrasound generated in the ultrasound transmitting medium;
• and
• an imaging system that displays the passive cavitation image using the ultrasound signal received by the imaging probe,
• wherein the imaging system is configured to perform:
• receiving the 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 (Delay And Sum) 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.
