PROBLEM TO BE SOLVED: To accurately simulate the structure and optical characteristics of tissue inside an object in a phantom for an object information acquiring apparatus.SOLUTION: A phantom used for calibrating an object information acquiring apparatus which irradiates an object with light and acquires characteristic information inside the object on the basis of acoustic waves transmitted from the object comprises: a base material and a simulated tissue portion which simulates a three-dimensional structure of tissue inside a living body, the simulated tissue portion being arranged inside the base material, and having a simulated layer, which is a layer simulating optical characteristics of the tissue inside the living body, on a surface thereof.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】被検体情報取得装置用のファントムにおいて、被検体内の構造および光学特性を精密に模擬する。【解決手段】被検体に光を照射し、前記被検体から伝播した音響波に基づいて前記被検体内部の特性情報を取得する被検体情報取得装置の校正に用いるファントムであって、母材と、生体内組織の立体構造を模擬した模擬組織部と、を有し、前記模擬組織部は、前記母材の内部に配置され、その表面に、前記生体内組織の光学特性を模擬した層である模擬層を有する。【選択図】図1
