An ultrasound imaging method includes steps of transmitting a plurality of ultrasound signals by a pulse repetition interval； receiving a plurality of reflected signals of the ultrasound signals； separating a blood flow signal and a clutter signal from the reflected signals by a neural network； calculating a blood flow parameter according to the blood flow signal； determining a blood vessel position according to the blood flow parameter； and adjusting an image signal corresponding to the reflected signals according to the blood flow parameter and the blood vessel position to generate an ultrasound image.一種超音波成像方法，包含下列步驟：以一脈衝重複時間間隔發射複數個超音波訊號；接收超音波訊號之複數個反射訊號；以一神經網路將反射訊號分離為一血流訊號以及一雜波訊號；根據血流訊號計算一血流參數；根據血流參數判斷一血管位置；以及根據血流參數以及血管位置調整反射訊號對應之一影像訊號，據以產生一超音波影像。
