PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic apparatus by which a three-dimensional image with a high image quality can be obtained even while suppressing the inside temperature rise in an ultrasound probe.SOLUTION: The inside temperature Tp of the ultrasound probe is detected by a temperature sensor (S3), usual scanning is carried out (S5) in the case the detected inside temperature Tp of the ultrasound probe is lower than the first set value T1 (S4), temperature rise suppressing scanning in which the transceiving or receiving of an ultrasound beam is carried out while reducing special resolution to an area of at least a part other than an area of interest (S9), three-dimensional image data is formed (S6), and thereafter the three-dimensional image is displayed (S7), in the case the inside temperature Tp is the first set value T1 or higher (S4).COPYRIGHT: (C)2013,JPO&INPIT【課題】超音波プローブの内部温度の上昇を抑制しながらも高画質の3次元超音波画像を得ることができる超音波診断装置を提供する。【解決手段】温度センサで超音波プローブの内部温度Tpを検出し(S3)、検出された超音波プローブの内部温度Tpが第1の設定値T1未満の場合は(S4)、通常走査を行って(S5)、また、第1の設定値T1以上の場合は(S4)、関心領域以外の少なくとも一部の領域に対して空間分解能を低下させて超音波ビームの送受信または受信が行われる温度上昇抑制型走査を行って(S9)、3次元画像データを生成した後(S6)、3次元画像を表示する(S7)。【選択図】図2
