PROBLEM TO BE SOLVED: To provide a photoacoustic imaging apparatus capable of receiving sufficient acoustic waves required for a detection of an analyte from a shallow part of the analyte immediately beneath a detection part.SOLUTION: A photoacoustic apparatus 100 comprises: a detection part 3 for detecting acoustic waves an LED light source part 1 (2) that is disposed close to the detection part 3, includes an LED light source 10 (20) outputting light to be applied to an analyte 90, and causes a detection object 90a of the analyte 90 to absorb the light applied to the analyte 90 and to generate an acoustic wave and a sealing part 6 that is configured to propagate the acoustic wave generated from the detection object 90a to the detection part 3 by sealing the surface of the detection part 3 located forward in the detection direction in a side where the analyte 90 is disposed with respect to the detection part 3, and that is disposed forward in the detection direction where the analyte 90 is disposed with respect to the detection part 3.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】検出部直下の被検体の浅い部分から被検体の検出に必要とされる十分な音響波を受信することが可能な光音響画像化装置を提供する。【解決手段】この光音響画像化装置100は、音響波を検出する検出部3と、検出部3に近接して配置され、被検体90に光を照射する光を出力するLED光源10(20)を含み、被検体90に照射した光を被検体90の検出対象物90aに吸収させることにより音響波を発生させるLED光源部1(2)と、検出部3に対して被検体90が配置される側の検出方向前方の検出部3の表面を封止することにより、検出対象物90aから発生される音響波を検出部3に伝搬するように構成され、検出部3に対して被検体90が配置される検出方向前方に配置される封止部6とを備える。【選択図】図2
