PROBLEM TO BE SOLVED: To solve the problem that, when a subject is pressed using a plate and an acoustic wave is received by a probe via the plate, the acoustic wave is refracted due to the difference between the sound velocity in the compression plate and the sound velocity in the subject, and a reduction in resolution occurs when the refraction is not considered.SOLUTION: In a biological information acquisition apparatus, a processing section 9 has a correction table 92 or a correction formula for correcting image distortion associated with refraction, and after acquiring image information, acquires new image information in accordance with the correction table 92 or the correction formula, and displays it.COPYRIGHT: (C)2010,JPO&INPIT【課題】 被検体をプレートで押さえ、プレート越しに探触子で音響波を受信すると、被検体とプレートに音速差があるため音響波が屈折し、その屈折を考慮しないと解像度低下が生じてしまう。【解決手段】 屈折に伴う画像の歪みを補正するための補正テーブルまたは補正式を設け、画像情報を取得してから、補正テーブルまたは補正式にしたがって新たな画像情報を取得して表示させる。【選択図】 図4
