PROBLEM TO BE SOLVED: To provide an ultrasonic measuring apparatus, an ultrasonic image apparatus, and an ultrasonic measuring method which achieve both high speed and high resolution and are easy to use.SOLUTION: An image is generated by adding a reception signal obtained by receiving an ultrasonic echo by an ultrasonic element array with weight of a fixed value, and a region of interest is set within a range on which the generated image is displayed. When the region of interest is acquired, image generation is performed by adding the reception signal received by the ultrasonic element array with the weight according to the reception signal for data to be the base of the image to be displayed in the region of interest.COPYRIGHT: (C)2015,JPO&INPIT【課題】高速化と高分解能化とを両立させた、使い勝手の良い超音波測定装置、超音波画像装置及び超音波測定方法を提供する。【解決手段】超音波エコーを超音波素子アレイで受信した受信信号を固定値の重みで加算して画像を生成し、生成された画像が表示される範囲内に関心領域を設定する。関心領域が取得されると、関心領域に表示される画像の基となるデータについては、超音波素子アレイで受信した受信信号を受信信号に応じた重みで加算して画像生成を行う。【選択図】図9
