SUBJECT INFORMATION ACQUISITION APPARATUS, AND SUBJECT INFORMATION ACQUISITION METHOD

PROBLEM TO BE SOLVED: To provide a subject information acquisition apparatus and a subject information acquisition method capable of reducing noise superimposed on a signal based on an acoustic wave, even when continuously moving a probe.SOLUTION: The subject information acquisition apparatus includes: a first detection element and a second detection element configured to receive acoustic waves propagated from a subject and output signals with polarities opposite to each other; and a signal processing unit configured to acquire information on the subject by using a differential signal based on a difference between the signals output from the first and the second detection elements.SELECTED DRAWING: Figure 2 【課題】 探触子を連続的に動かした場合にも、音響波に基づく信号に重畳されるノイズを低減できる被検体情報取得装置および被検体情報取得方法を提供する。【解決手段】 被検体情報取得装置は、被検体から伝播した音響波を受信して互いに逆の極性の信号を出力する第１および第２の検出素子と、第１および第２の検出素子から出力された信号の差分に基づく差分信号を用いて、被検体の情報を取得する信号処理部と、を有する。【選択図】 図２
