OBJECT INFORMATION ACQUIRING APPARATUS AND CONTROL METHOD THEREOF

摘要

Provided is an object information acquiring apparatus including: a holding unit that holds an object; a probe that receives an acoustic wave that propagates from the object; a housing that constitutes a holding container; a matching solution that is filled inside the holding container; and a pressure adjustment unit including a liquid quantity adjustment section that adjusts the quantity of the matching solution, and a distance adjustment section that adjusts the distance between the holding container and the object, wherein the pressure adjustment unit performs a first compression which increases a pressure applied to the object to a predetermined pressure value, and then performs a second compression which maintains the predetermined pressure value, while decreasing the liquid quantity inside the holding container.

1. An object information acquiring apparatus comprising:
a holding unit configured to hold an object; a probe configured to receive, via the holding unit, an acoustic wave that propagates from the object held by the holding unit; a housing configured to, along with the holding unit, constitutes a holding container; a matching solution configured to be filled inside the holding container and to match acoustic impedance between the holding unit and the probe; and a pressure adjustment unit including a liquid quantity adjustment section configured to adjust a quantity of the matching solution inside the holding container, and a distance adjustment section configured to adjust a distance between the holding container and the object, wherein the pressure adjustment unit performs a first compression which increases a pressure applied to the object to a predetermined pressure value while adjusting the distance adjustment section without adjusting the liquid quantity adjustment section, and then performs a second compression which maintains the predetermined pressure value by decreasing the distance between the object and the holding container using the distance adjustment section, while decreasing the liquid quantity inside the holding container using the liquid quantity adjustment section.
