PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic apparatus which enables appropriate monitoring of a puncture needle, and an ultrasound probe.SOLUTION: The ultrasound diagnostic apparatus generates image data including a puncture needle, based on needle visibility-preferred image data generated based on reception signals of ultrasound waves output in a needle visibility-preferred mode which disables the transmission/reception of ultrasound waves to/from a transducer region 210b including at least a central portion in a short axis direction but enables the transmission/reception of ultrasound waves to/from transducer regions 210a, 210c. The ultrasound diagnostic apparatus generates combined image data, based on image quality-preferred image data generated based on reception signals of ultrasound waves output in an image quality-preferred mode which enables the transmission/reception of ultrasound waves to/from at least the transducer region 210b and on the needle visibility-preferred image data.SELECTED DRAWING: Figure 4B【課題】穿刺針を好適にモニタリングすることができる超音波診断装置および超音波探触子を提供する。【解決手段】少なくとも短軸方向の中央部を含む振動子領域２１０ｂから超音波を送受信させず、振動子領域２１０ａ，２１０ｃから超音波を送受信させる針視認優先モードで出力された超音波の受信信号に基づいて生成された針視認優先画像データに基づいて、穿刺針を含む画像データを生成し、少なくとも振動子領域２１０ｂから超音波を送受信させる画質優先モードで出力された超音波の受信信号に基づいて生成された画質優先画像データと針視認優先画像データとに基づいて合成画像データを生成する。【選択図】図４Ｂ
