PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus or the like which reduces workload for Doppler measurement of the circulatory organs, improves working efficiency, and reduces variations in measurement results by automating or semi-automating various procedures accounting for most of operations for Doppler measurement of the circulatory organs.SOLUTION: When a dropout portion is present in a trace waveform, the trace waveform is automatically corrected by causing an operator to set at least one desired estimated point in consideration of individual differences and the types of valves and interpolating the dropout portion by using the set estimated point, marginal information of the trace waveform having the dropout portion, and a predetermined function.COPYRIGHT: (C)2010,JPO&INPIT【課題】循環器ドプラ計測における作業の大半を占めていた種々の手技を自動化又は半自動化することができ、循環器ドプラ計測における作業負担の軽減、作業効率の向上、計測結果のばらつきの低減に寄与することができる超音波診断装置等を提供すること。【解決手段】トレース波形に欠落部分が存在する場合に、操作者に個体差や弁の種類を考慮して所望の推定点を少なくとも一つ設定させ、設定された推定点と、欠落のあるドレース波形の辺縁情報と、所定の関数とを用いて欠落部位を補間し、トレース波形を自動的に補正するものである。【選択図】 図5
