PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment capable of striking a high-level balance between noise reduction and resolution improvement.SOLUTION: Ultrasonic diagnostic equipment includes a smoothing processing part 83 for executing a weighting processing using data of each point and data of a peripheral point of each point, concerning each data of a real part and an imaginary part of a self-correlation vector of each point calculated by a correlation computation part 53, and power data of each point, which is a weighting averaging process using weights determined by enlarging the weight of data of each point and by reducing the weight of data of the peripheral point of each point, in proportion to largeness of the power defined as a variable of the power of each point.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2019,JPO&INPIT【課題】ノイズの低減と分解能の向上を高いレベルで両立させた超音波診断装置を提供する。【解決手段】相関演算部53で算出された、各点の自己相関ベクトルの実部および虚部の各々のデータ、並びに、各点のパワーのデータについて、各点のデータと各点の周囲の点のデータとを用いた重み付け処理であって、かつ、各点のパワーの変数として定義されパワーが大きいほど各点のデータの重みが大きく各点の周囲の点のデータの重みを小さくした重みを用いた重み付け平均化処理を実行する平滑化処理部83を備えた。【選択図】図5
