PROBLEM TO BE SOLVED: To achieve accurate fetus measurement more easily and simply in an ultrasonic diagnostic device.SOLUTION: A reference cross section 44 that crosses a measurement object part (e.g., a head) in a fetus 42 is set, and a scan range 46 for search as a three-dimensional range that spreads in the front and the rear of the reference cross section 44 is set. Volume data for search is acquired by the transmission and reception of an ultrasonic wave to and from the scan range 46 for search, and based on the volume data for search, a measurement surface including a predetermined cross section of the measurement object part is searched. A scan range for measurement including the measurement surface is set, and by the transmission and reception of the ultrasonic wave to and from the scan range for measurement, measurement surface data (e.g., B mode tomographic image data) is acquired. Based on the measurement surface data, measurement for the measurement object part is performed.SELECTED DRAWING: Figure 10COPYRIGHT: (C)2017,JPO&INPIT【課題】超音波診断装置において、より簡便に精度の高い胎児計測が実現されるようにする。【解決手段】胎児42における計測対象部分(例えば頭部)を横切る基準断面44が設定され、その基準断面44の前後に広がる三次元範囲としての探索用スキャン範囲46が設定される。探索用スキャン範囲46に対する超音波の送受波により探索用ボリュームデータが取得され、その探索用ボリュームデータに基づいて、計測対象部分の所定断面を含む計測面が探索される。その計測面を含む計測用スキャン範囲が設定され、その計測用スキャン範囲に対する超音波の送受波により計測面データ(例えばBモード断層画像データ)が取得され、その計測面データに基づいて計測対象部分に対する計測が実行される。【選択図】図10
