PROBLEM TO BE SOLVED: To improve an ultrasonic image even if frequency characteristics vary between respective vibration elements of an ultrasonic probe.SOLUTION: An ultrasonographic device includes the ultrasonic probe including a plurality of vibration elements that send and receive ultrasonic waves, and a receiving unit that receives a reflected wave received by the vibration elements as echo reception signals. Moreover, the ultrasonographic device includes a storage unit where the frequency characteristics of the vibration elements are measured in advance and stored, and a correction unit that corrects the echo reception signals of the respective vibration elements, based on the frequency characteristics of the vibration elements stored in the storage unit.COPYRIGHT: (C)2013,JPO&INPIT【課題】超音波探触子の各振動素子間で周波数特性のばらつきがあったとしても、超音波画像の画質を向上する。【解決手段】超音波の送受波を行う振動素子を複数備えた超音波探触子と、前記振動素子で受波した反射波をエコー受信信号として受信する受信部とを備えた超音波診断装置であって、前記各振動素子の周波数特性が予め測定されて記憶された記憶部と、該記憶部に記憶された前記各振動素子毎の周波数特性に基づいて、前記各振動素子毎のエコー受信信号を補正する補正部とを備える。【選択図】図9
