To present appropriate information to an operator and a pregnant woman, when an unborn child is in a specific condition such as breech presentation, during unborn child examination.SOLUTION: An ultrasonic diagnostic apparatus according to an embodiment has determination means, calculation means and generation means. The determination means determines an unborn child condition. The calculation means calculates a plurality of estimated unborn child weights by applying a measured value to a plurality of estimated weight formulas, when the determination means determines that the unborn child condition is in a specific condition. The generation means generates a superimposed image in which the plurality of estimated unborn child weights are superimposed on an unborn child growth curve, and causes a display part to display the superimposed image.SELECTED DRAWING: Figure 3【課題】胎児検査時に胎児が骨盤位等の特定の状態にある場合に、操作者及び妊婦に適切な情報を提示すること。【解決手段】実施形態に係る超音波診断装置は、判定手段と、算出手段と、生成手段とを有する。判定手段は、胎児の状態を判定する。算出手段は、判定手段によって胎児の状態が特定の状態であると判定された場合、計測値を複数の推定体重式に適用することで複数の推定胎児体重を算出する。生成手段は、複数の推定胎児体重が胎児発育曲線に重畳された重畳画像を生成して、重畳画像を表示部に表示させる。【選択図】 図3
