PROBLEM TO BE SOLVED: To provide a system and a method for ultrasonic image optimization.SOLUTION: A first ultrasonic signal which has two or more first signal parameters, is transmitted to the inside of an object, a first set of electric signals are received, and a first image is acquired. A first image quality measurement amount is formed by evaluating an image quality cost function about the first image (88), and two or more second signal parameters are decided based on the first image quality measurement amount (90). A second ultrasonic signal which has two or more second signal parameters, is transmitted to the inside of the object, a second set of electric signals are received, and a second image is acquired (96). A second image quality measurement amount is formed by evaluating an image quality cost function about the second image (98), in order to determine whether a maximization image quality measurement amount is reached, the first image quality measurement amount and the second image quality measurement amount are compared (100), and the object is imaged with two or more signal parameters, which form the maximization image quality measurement amount, as an optimal parameter (104) and is displayed (106).COPYRIGHT: (C)2011,JPO&INPIT【課題】超音波画像最適化のためのシステム及び方法を提供する。【解決手段】対象内に第1の複数の信号パラメータを有する第1の超音波信号を送信して第1組の電気信号を受信し、第1の画像を得る。第1の画像に関する画質コスト関数を評価して第1の画質計測量を生成(88)し、かつ該第の画質計測量に基づいて第2の複数の信号パラメータを決定(90)する。対象内に第2の複数の信号パラメータを有する第2の超音波信号を送信し、第2組の電気信号を受信し、第2の画像を得る(96)。第2の画像に関する画質コスト関数を評価して第2の画質計測量を生成し(98)、最大化画質計測量に到達したか否かを判定するために第1の画質計測量と第2の画質計測量を比較し(100)、最大化画質計測量を生成させた複数の信号パラメータを最適なパラメータとして対象を撮像(104)し表示(106)する。【選択図】図2
