Title (EN) INFORMATION ACQUISITION DEVICE AND SIGNAL PROCESSING METHOD
(FR) DISPOSITIF D’ACQUISITION D’INFORMATIONS ET PROCÉDÉ DE TRAITEMENT DE SIGNAL
(JA) 情報取得装置および信号処理方法
Abstract:
(EN) Provided is an information acquisition device which acquires characteristic information of a subject using a received signal of an acoustic wave which is emitted from the subject which is illuminated with light. Said information acquisition device comprises: a region acquisition means which acquires information which indicates a plurality of regions within the subject which have mutually different characteristics; an acoustic velocity determination means which determines an acoustic velocity for each of the plurality of regions using the information which indicates the plurality of regions; and a characteristic information acquisition means which acquires characteristic information of the subject using the acoustic velocity and the received signal.
(FR) La présente invention concerne un dispositif d’acquisition d’informations qui acquiert des informations caractéristiques d’un sujet au moyen d’un signal reçu d’une onde acoustique qui est émise par le sujet qui est éclairé avec de la lumière. Ledit dispositif d’acquisition d’informations comprend : un moyen d’acquisition de région qui acquiert des informations qui indiquent une pluralité de régions dans le sujet qui ont des caractéristiques mutuellement différentes ; un moyen de détermination de vitesse acoustique qui détermine une vitesse acoustique pour chacune de la pluralité de régions au moyen des informations qui indiquent la pluralité de régions ; et un moyen d’acquisition d’informations caractéristiques qui acquiert des informations caractéristiques du sujet au moyen de la vitesse acoustique et du signal reçu.
(JA) 光を照射された被検体から発生する音響波の受信信号を用いて、被検体の特性情報を取得する情報取得装置であって、被検体における、特性が互いに異なる複数の領域を示す情報を取得する領域取得手段と、複数の領域を示す情報を用いて、複数の領域のそれぞれの音速を決定する音速決定手段と、音速と受信信号とを用いて、被検体の特性情報を取得する特性情報取得手段を有する情報取得装置を用いる。
