PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device which edits an ultrasonic image signal and displays an exercise state in a region to be measured so that it is visually understandable.SOLUTION: The ultrasonic diagnostic device includes: an image data generation means 117 for generating image data which represent an ultrasonic image about a blood vessel of the body under test an object setting part 125 for setting a region to be measured in the ultrasonic image a position identification part 127 for demarcating a measurement position in the region to be measured a display processing part 121 for forming a picture which displays changes over time of the region to be measured to a three-dimensional coordinate system including a time axis and a display device 123. Changes over time of the region to be measured is three-dimensionally displayed to the three-dimensional coordinate system including the time axis.COPYRIGHT: (C)2010,JPO&INPIT【課題】超音波画像信号を編集して測定対象領域の運動状態を視覚的に理解しやすく表示する超音波診断装置を提供する。【解決手段】この超音波診断装置は、被検体の血管に関する超音波画像を表す画像データを生成する画像データ生成手段117と、超音波画像中に測定対象領域を設定する対象設定部125と、測定対象領域の測定位置を画定する位置特定部127と、時間軸を含む3次元座標系に測定対象領域の経時変化を表示する画面を形成する表示処理部121と、表示装置123とを具備して、時間軸を含む3次元座標系に測定対象領域の経時変化を立体的に表示する。【選択図】図1
