Zusammenfassung:To provide an ultrasonic imaging device that quantifies manipulation of a probe by an operator when the probe is moved over the surface of a subject.SOLUTION: An ultrasonic imaging device 3 comprises: an ultrasonic receiving unit 351 that receives, via a probe disposed on a surface of the subject, signals pertaining to ultrasonic waves transmitted by the probe into the subject and reflected inside the subject; image generating units 352 and 353 that generate ultrasonic images on the basis of the signals of the received ultrasonic waves; and a pressing force estimating unit 354 that estimates, on the basis of the displacements of positions of corresponding feature points, a pressing force indicator that is an indicator representing the magnitude of a contact force on the subject due to the probe, in two or more ultrasonic images which are acquired at a plurality of probe positions on the surface of the subject and partially overlap each other.SELECTED DRAWING: Figure 5 【課題】被検体表面に沿ってプローブを移動させる際のオペレータによるプローブの手技を定量化する超音波撮像装置を提供する。【解決手段】超音波撮像装置3は、被検体の表面に配置されたプローブから被検体の内部に送信されて、被検体の内部で反射された超音波に関する信号を、プローブを通じて受信する超音波受信部351と、受信した超音波の信号に基づいて超音波画像を生成する画像生成部352,353と、被検体の表面上の複数のプローブ位置において取得された、互いに少なくとも一部の撮像領域が重なる2枚以上の超音波画像間における、対応する特徴点の位置の変位に基づいて、プローブによる被検体への接触圧の大きさを示す指標である押圧指標を推定する押圧推定部354と、を備える。【選択図】図5
