PROBLEM TO BE SOLVED: To provide an ultrasonic bone assessment device capable of obtaining the appropriate calibration value with a simple device configuration.SOLUTION: The ultrasonic bone assessment device, which transmits and receives ultrasonic waves to a living body placed on a mounting table and evaluates the intravital bone, includes: a pair of ultrasound transducers 34 arranged to hold the living body placed on the mounting table therebetween a pair of matching-material bags 18 each of which is located between the ultrasound transducer 34 and living body, and houses an acoustic matching material therein and a communication passage 44 which is located between the matching-material bags 18 and allows an internal space between the pair of matching-material bags 18 to communicate with each other. The ultrasonic waves are transmitted and received by the pair of ultrasound transducers 34 at the position where the bone of the assessment target is held and also the position where the communication passage 44 is held therebetween.COPYRIGHT: (C)2012,JPO&INPIT【課題】本発明は、簡易な装置構成で適正な校正値を得ることができる超音波骨評価装置を提供することを目的とする。【解決手段】本発明は、載置台上に載置された生体に対して超音波を送受して生体内の骨の評価を行う超音波骨評価装置であって、前記載置台に載置された生体を挟むように配置される一対の超音波振動子34と、超音波振動子34と生体の間に位置し、音響整合材を収容した一対の整合材袋18と、整合材袋18間に位置し、一対の整合材袋18同士の内部空間を連通させる連通路44と、を備え、一対の超音波振動子34を評価対象の骨を挟む位置と、連通路44を挟む位置において超音波を送受する。【選択図】図5
