摘要：
PROBLEM TO BE SOLVED: To provide a reception data processing device for photoacoustic tomography, capable of performing image reconstruction for the photoacoustic tomography at high speed with a small-sized configuration, by using a characteristic of the photoacoustic tomography.SOLUTION: A reception data processing device for photoacoustic tomography comprises: minimum construction unit data combination means for combining minimum construction unit data on an acoustic wave in each minimum construction unit in a subject area, by sequentially reading out reception digital signals derived from each minimum construction unit from first storage means to perform phasing addition on the signals on the basis of information on a delay of an acoustic wave from each minimum construction unit to each acoustic wave receiving element second storage means capable of storing minimum construction unit data on the whole subject area image construction means for constructing an image of a subject on the basis of the minimum construction unit data stored in the second storage means and control means for sequentially storing, in the second storage means, each minimum construction unit data calculated by the minimum construction unit data combination means, and reading the stored minimum construction unit data on the whole subject area to transmit the read data to the image construction means.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】光音響トモグラフィの特質を活用し、小規模な構成で、高速に光音響トモグラフィの画像再構成を行いうる光音響トモグラフィの受信データ処理装置を提供する。【解決手段】被検体領域の各最小構成単位から各音響波受信素子への音響波の遅延情報に従い、第一の記憶手段より各最小構成単位由来の受信デジタル信号を順次読み出し整相加算して各最小構成単位における音響波の最小構成単位データを合成する最小構成単位データ合成手段と、被検体領域全体の最小構成単位データを保存可能な第二の記憶手段と、第二の記憶手段に保存された最小構成単位データに基づき被検体の画像を構成する画像構成手段と、最小構成単位データ合成手段によって演算された各最小構成単位データを順次第二の記憶手段に記憶し、記憶された被検体領域全体の最小構成単位データを読み出して画像構成手段に送る制御手段と、を具備してなる。【選択図】図1
