PROBLEM TO BE SOLVED: To perform ultrasonic imaging with a high bubble tissue ratio and high depth sensitivity.SOLUTION: An ultrasonic diagnostic device of an embodiment includes a transceiver unit, an addition/subtraction unit, and an image generation unit. In the same scan line of a photographic site of a subject whereto a contrast medium is applied, the transceiver unit carries out a plurality of sets of ultrasonic transmission and receiving of a first set in which ultrasonic transmission with modulated amplitude or phase is performed for two or more times and reflected waves are received and ultrasonic transmission and receiving of a second set in which phase modulation is different from that of the ultrasonic transmission and receiving of the first set, and outputs reflected wave data for the plurality of sets. The addition/subtraction unit either adds or subtracts the reflected wave data for the plurality of sets. The image generation unit generates contrast image data on the basis of data output from the addition/subtraction unit.COPYRIGHT: (C)2014,JPO&INPIT【課題】超音波造影を高いバブル組織比と高い深部感度とで行なうこと。【解決手段】実施形態の超音波診断装置は、送受信部と、加減算部と、画像生成部とを備える。送受信部は、造影剤が投与された被検体の撮影部位の同一走査線上において、振幅又は位相を変調させた超音波送信を複数回行なって反射波を受信する第1セットの超音波送受信と、第1セットの超音波送受信とは位相変調が異なる第2セットの超音波送受信とを、複数セット行なって複数セット分の反射波データを出力する。加減算部は、複数セット分の反射波データを加算又は減算する。画像生成部は、加減算部から出力されたデータに基づいて、造影画像データを生成する。【選択図】図2
