To provide a Doppler signal collection device capable of easily and quickly tracking a target located in a subject.SOLUTION: A Doppler signal collection device comprises: a reception unit 107 for receiving distribution information, which is information indicating a distribution on a Doppler signal component of a reflection wave with respect to an ultrasonic wave radiated on a subject; an acquisition unit 109 for acquiring an azimuth angle and distance of a target located in the subject, by using the distribution information; and an output unit 110 for performing output of information depending on the azimuth angle and distance of the target acquired by the acquisition unit 109. The acquisition unit 109 repeats processing of acquiring the azimuth angle of the target using the distribution information received by the reception unit 107, after the distance of the target is acquired. The output unit 110 outputs information depending on the azimuth angle acquired by the acquisition unit 109, after the distance of the target is acquired.SELECTED DRAWING: Figure 1 【課題】容易にかつ迅速に被検体内に位置する目標を追尾することができるドプラ信号採取装置を提供する。【解決手段】被検体に照射された超音波に対する反射波のドプラ信号成分に関する分布を示す情報である分布情報を受け付ける受付部１０７と、分布情報を用いて、被検体内に位置する目標の方位角と距離とを取得する取得部１０９と、取得部１０９が取得した目標の方位角と距離とに応じた情報の出力を行なう出力部１１０とを備え、取得部１０９は、目標の距離の取得後に、受付部１０７が受け付ける分布情報を用いて目標の方位角を取得する処理を繰り返し、出力部１１０は、目標の距離の取得後に、取得部１０９が取得した方位角に応じた情報の出力を行うようにした。【選択図】図１
