PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment that reliably recognizes a static operation of a probe, and reliably performs an operation corresponding to a static state.SOLUTION: Ultrasonic diagnostic equipment includes: a phasing and adding unit 22 for generating frame data on a subject 18 sequentially with time based on an ultrasonic wave reflected by the subject 18 and received by a probe 14 a tracking processing unit 36 for executing tracking processing for a determination region on an observation region indicated by the frame data generated first, and searching for a movement destination region corresponding to the determination region within a tracking region set for the observation region indicated by the frame data generated later and static operation determination unit 38 for determining whether or not there is a static operation for the probe 14 based on an approximation degree between the determination region and the movement destination region.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】探触子の静止操作を確実に認識し、静止状態の対応した動作を確実に行える超音波診断装置を提供する。【解決手段】被検体18で反射し探触子14で受信された超音波に基づいて、被検体18についてのフレームデータを時間経過と共に順次生成する整相加算部22と、先に生成されたフレームデータが示す観測領域上の判定領域に対する追跡処理を実行し、後に生成されたフレームデータが示す観測領域に設定された追跡範囲内で、判定領域に対応する移動先領域を探索する追跡処理部36と、判定領域と移動先領域との近似度に基づいて、探触子14に対する静止操作があったか否かを判定する静止判定部38と、を備える。【選択図】図1
