The medical ultrasonic imaging diagnostic equipment obtains the ultrasonic characteristic information of human tissues and organ structures by using the transmission of ultrasonic waves in a human body. The current ultrasonic imaging diagnostic equipment usually adopts a multi-array element probe, high-voltage pulse waves are loaded on each array element probe, and array elements are excited to generate high-frequency ultrasonic waves so as to form transmitting beams to enter a human body. The probes of each array element receive the scattered or reflected echo of the human tissue structure to form a receiving beam, and the ultrasonic diagnosis system extracts the information in the ultrasonic echo to form various imaging.
Pulse wave spectral Doppler imaging (PW imaging for short) transmits ultrasonic pulse signals at fixed time intervals through an ultrasonic front end to enter human target tissues, Doppler frequency shift information of the ultrasonic pulse signals is detected, the frequency spectrum of the ultrasonic pulse signals is acquired in real time, and a Doppler frequency spectrogram containing information related to motion of the human tissues or blood flow is finally displayed.

In addition, when the display array has a display fault, the display array cannot be detected in time to determine the fault position.
