The present invention is capable of warming to the living body deep, to provide a heating device for fat diagnostic also difficult to create a safety hazard to use in the vicinity of the bone tissue. Configuration and a coil 11 disposed around the transmission and reception surface for transmitting and receiving ultrasonic waves of An ultrasonic diagnostic probe 20, from the high frequency power source 12 for applying a high frequency power for biological heating the coil by using an ultrasonic diagnostic probe 20 measures the ultrasound echo signals before and after heating of the measurement region and performs the fat diagnosis based on ultrasound velocity variation calculated from the heating before and after the ultrasonic echo signal.FIELD 1【課題】生体深部への加温が可能であり、骨組織の近傍で使用しても安全上の問題が生じにくい脂肪診断用の加温装置を提供する。【解決手段】超音波診断用プローブ20の超音波を送受する送受面の周囲に配置されるコイル11と、コイルに生体加温用の高周波電力を印加する高周波電源12とから構成され、超音波診断用プローブ20を用いて測定領域の加温前後の超音波エコー信号を計測し、加温前後の超音波エコー信号から算出した超音波速度変化に基づいて脂肪診断を行う。【選択図】図1
