ABSTRACT:
An ultrasonic imaging device for transmitting/receiving ultrasonic pulses to/from a living body in which microbubbles for contrast are introduced and forming a contrast image of the inside of the living body by using the microbubble for contrast, wherein transmitting/receiving operations are performed N times (N=an integer of three or greater) by using transmission pulse waves having a common envelope signal while varying carrier waves in phase by 360°/N from one wave to another under the same transmission/reception wave focus condition, and by summing N pieces of time-series reception echo signals obtained by the N times of transmitting/receiving operations to obtain a summed signal, thereby forming the contrast image.
