Summary:PROBLEM TO BE SOLVED: To provide a technique to cope with a change in an attenuation amount according to a position of a probe in a device for receiving an ultrasonic wave from a subject while scanning the probe and acquiring characteristic information.SOLUTION: A subject information acquisition device includes: a reception unit where a plurality of elements that receive an acoustic wave propagating from a subject and output an electric signal are arranged; a scan unit that moves the reception unit in a predetermined scan region; an information processing unit for acquiring characteristic information in the subject using the electric signal; and a sound attenuation unit arranged between the reception unit and the subject in the scan region that has a sound attenuation characteristic distribution according to the shape of the subject.SELECTED DRAWING: Figure 1 【課題】探触子を走査しながら被検体からの超音波を受信して特性情報を取得する装置において、探触子の位置に応じた減衰量の変化に対応するための技術を提供する。【解決手段】被検体から伝搬する音響波を受信して電気信号を出力する複数の素子を配列した受信部と、受信部を所定の走査領域において移動させる走査部と、電気信号を用いて被検体内の特性情報を取得する情報処理部と、前記走査領域において、前記受信部と前記被検体との間に配置され、被検体の形状に応じた音響減衰特性分布を有する音響減衰部と、を有する被検体情報取得装置を用いる。【選択図】図１
