SUBJECT INFORMATION ACQUIRING APPARATUS

摘要

A subject information acquiring apparatus of the present invention includes a subject-holding member which holds a subject and a probe unit having a transducer which receives acoustic waves from the subject through the subject-holding member, a housing which accommodates the transducer, and a matching liquid-holding member configured to hold a matching liquid between the transducer and the subject-holding member, the probe unit being allowed to move relative to the subject-holding member. The probe unit has a guide which introduces the matching liquid to the subject-holding member, the matching liquid having been spilled from a space defined by the matching liquid-holding member, the transducer, and the subject-holding member onto the upper surface of the hosing and then flowed from the upper surface of the housing.

主权项

1. A subject information acquiring apparatus comprising:
a subject holding member which holds a subject; and a probe unit having a housing having an opposing surface facing to the subject holding member and an upper surface connected to an upper edge of the opposing surface, a transducer provided on the opposing surface and a matching liquid storing member secured to the opposing surface and contacting the subject holding member so as to form a storing space storing a matching liquid between the opposing surface and the subject holding member, wherein the opposing surface has a supply port being configured to supply the matching liquid to the storing space and the matching liquid storing member has an opening between the supply port and the upper surface, and wherein the probe unit has a guide which directs the matching liquid overflowed from the storing space via the opening to the subject holding member.
