PROBLEM TO BE SOLVED: To acquire information useful for evaluating cardiac functions of fetuses.SOLUTION: An ultrasound diagnostic apparatus according to the embodiment includes a collection unit and an acquisition unit. The collection unit collects moving images which include the heart of a fetus, on the basis of two- or three-dimensional luminance signals. The acquisition unit acquires a reference waveform that makes it possible to estimate a cardiac phase of the fetus, on the basis of the moving images.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】胎児の心機能評価に有用な情報を得ること。【解決手段】実施形態の超音波診断装置は、収集部と、取得部とを備える。収集部は、胎児心臓が含まれる２次元又は３次元の輝度信号に基づく動画像を収集する。取得部は、前記動画像に基づいて、胎児心時相を推定可能な参照波形を取得する。【選択図】図１
