Summary:To provide a method and a measurement apparatus for measuring behaviors of ultrasound waves in a mode different from that of a reflection image.SOLUTION: An ultrasound measurement method and a measurement apparatus for a measurement object include: contacting an ultrasound probe including a projection transducer group having three or more transducers and a reception transducer group having a plurality of transducers with a measurement object such that the ultrasound probe passes through the inside of the measurement object from the projection transducer group to the reception transducer group; causing each of the transducers in the projection transducer group to sequentially project an ultrasound wave to inside the measurement object and causing respective transducers in the reception transducer group to receive the ultrasound wave projected by the respective transducer in the projection transducer group and transmitted through the measurement object as the reception data of each of the projecting transducers; and calculating the intensity attenuation of the ultrasound wave and the propagation velocity of the ultrasound wave at each position inside the measurement object by applying an aperture synthesis method on the basis of the reception data.SELECTED DRAWING: Figure 1 【課題】反射像とは異なるモードの超音波への挙動を把握する方法および測定装置の提供。【解決手段】３つ以上の振動素子を有する照射用振動素子群と、複数の振動素子を有する受信用振動素子群と、を有する超音波プローブを、照射用振動素子群から受信用振動素子群へと測定対象物の内部を通過するように、前記超音波プローブを測定対象物に当接させ、照射用振動素子群の振動素子を順々に超音波を測定対象物の内部に照射し、測定対象物を透過した超音波を、照射した振動素子ごとに各々の受信データとして受信用振動素子群の振動素子にそれぞれ受信させ、受信データに基づいて開口合成法を適用することにより、測定対象物の内部の各位置における超音波の強度減衰と超音波の伝播速度とを算出する、測定対象物の超音波測定方法方法及び装置。【選択図】図１
