The current ultrasonic imaging diagnostic equipment usually uses multi-array element probes. High-voltage pulse waves are loaded on each array element probe, and the array elements are excited to generate high-frequency ultrasonic waves to form emission beams that enter the human body. Each array element probe receives the echoes scattered or reflected by the human tissue structure to form a receiving beam, and the ultrasonic diagnostic system extracts the information in the ultrasonic echoes to form various images.
脉冲波频谱多普勒成像(简称PW成像)通过超声前端每隔固定时间发射超声脉冲信号进入人体目标组织，检测其多普勒频移信息，并实时获取其频谱，最终显示多普勒频谱图，其包含与人体组织运动或血液流动的相关信息。Pulse wave spectral Doppler imaging (PW imaging for short) transmits ultrasonic pulse signals into human target tissue at regular intervals through the ultrasonic front end, detects its Doppler frequency shift information, obtains its spectrum in real time, and finally displays the Doppler spectrogram , which contains information related to tissue movement or blood flow in the body.

In addition, when a display failure occurs in the display array, timely detection cannot be performed to determine the failure location.
