automatic detection method and system for sensitivity of ultrasonic probe on basis of lens echoes

The invention discloses an automatic detection method and system for the sensitivity of an ultrasonic probe on the basis of lens echoes, and relates to an automatic detection method for the sensitivity of the ultrasonic probe on the basis of the lens echoes. The automatic detection method comprises the following steps: S11, starting an automatic scanning mode for the sensitivity of the ultrasonicprobe, and acquiring electric signal data Sk (t) of lens echoes on the surface of each array element lens of the ultrasonic probe; S12, calculating a peak value P of a lens echo peak according to theacquired electric signal data Sk (t); and S13, judging whether the peak value P of the lens echo peak is greater than a preset threshold value of the sensitivity of the ultrasonic probe or not, and ifso, quitting the automatic scanning mode for the sensitivity; and if not, reminding a user to replace the ultrasonic probe. According to the invention, after a system is started, the system automatically enters the automatic s
