<p><P>PROBLEM TO BE SOLVED: To provide an acoustic matching member which can be easily replaced and in which air is hardly mixed in a biological information acquisition apparatus. <P>SOLUTION: The biological information acquisition apparatus includes: a plate which maintains the shape of a subject; the acoustic matching member which is arranged between the subject and the plate; and a probe which receives an acoustic wave propagating in the subject through the acoustic matching member and the plate. The acoustic matching member includes a first part which makes contact with the subject and a second part which makes contact with the plate. The second part is an elastic body which exhibits a rigidity higher than that of the first part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
