An ultrasonic probe, an ultrasonic imaging system and use method for biopsy needle visualization enhancement

An ultrasonic imaging system, comprising:

• an ultrasonic transmitting module, used for generating a transmit pulse;
• an ultrasonic probe, comprising a center element array and lateral element arrays, and used for transmitting the transmit pulse generated by the ultrasonic transmitting module in a form of an acoustic wave signal and receiving a returned acoustic wave signal, and converting the returned acoustic wave signal into a corresponding electronic signal;
• an ultrasonic receiving module, used for receiving the electronic signal returned by the ultrasonic probe and performing signal processing and image display;
• and
• a user interface, used for controlling a system control unit to perform a corresponding operation.

An operating method of an ultrasonic imaging system, comprising the following specific processes:

• S01, turning on a center element array only to scan a target object under a normal imaging mode to acquire a clear ultrasonic image;
• S02, finding a target region for tissue needle biopsy or interventional surgery through real-time scanning;
• S03, inserting a surgical needle into the target region of a human tissue;
• S04, turning on lateral element arrays to get into a needle body capturing mode with a thickened effective acoustic field wherein the thickened direction is perpendicular to the array element arrangement direction, so as to quickly find and capture a needle body of the needle;
• S05, manipulating the probe and the needle body to capture the needle body;
• and
• S06, determining whether the needle body is found, and continuing the operation of S05 if the needle body is not found;
• and if the needle body is found, moving the ultrasonic probe such that the needle body moves toward an acoustic field generated by the center element array, to complete the capturing of the target needle body.
