Image geometry distortion is an important technical standard in B-mode ultra-sound diagnosis system. This paper investigates the cause of image distortion in phased array B-mode ultrasound diagnosis system. The first distortion cause is the delay error of compound wave bind. Phased array ultrasound tranducer is composedof many rectangle units .With controlling inspiring plus time, ultrasound wave
