发明名称 Object information acquiring apparatus
摘要 An object information acquiring apparatus has: a holding unit which holds an object; a probe which receives an acoustic wave generated in the object via the holding unit and converts the acoustic wave to an electrical signal; a force measuring unit which measures a force applied to the object when the object is held by the holding unit; a sound speed acquiring unit which determines a sound speed in the object by using the force measured by the measuring unit and a contact area between the object and the holding unit; and a generating unit which generates object information data from the information about the sound speed determined by the sound speed acquiring unit and the electrical signal.

主权项 1. An object information acquiring apparatus, comprising: a holding unit configured to hold an object, wherein said holding unit includes two plates and being configured to compress and hold the object by said two plates; a probe configured to receive an acoustic wave generated in the object via said holding unit and convert the acoustic wave to an electrical signal; a force measuring unit configured to measure a force applied to the object when the object is held by said holding unit; an area measuring unit configured to measure a contact area between the object and said holding unit; a distance measuring unit configured to measure a distance between said two plates; and a sound speed acquiring unit configured to acquire a sound speed in the object by using the force measured by said force measuring unit, the contact area between the object and said holding unit measured by said area measuring unit, and the distance between said two plates as measured by said distance measuring unit before and after said two plates compress the object.
