Method, apparatus and system for imaging in ultrasonic scanning

An ultrasound imaging system, comprising:

• an ultrasound probe which comprises at least one ultrasound transducer group;
• a transmitting and receiving circuit which excites the ultrasound probe to transmit an ultrasound beam to a target tissue and receive echoes of the ultrasound beam to obtain echo signals;
• a memory which stores a computer program;
• a processor which executes the computer program in the memory to:
• control the ultrasound probe through the transmitting and receiving circuit to generate a shear wave in a target tissue which propagates in a region of interest in a shear wave propagation direction;
• select at least one ultrasound transducer group in the ultrasound probe and determine a focus point and a transmitting aperture of the ultrasound transducer group according to a depth and a width of the region of interest in the target tissue, such that a sound field generated by the at least one ultrasound transducer group completely covers the region of interest in the target tissue;
• control the transducers in the ultrasound transducer group through the transmitting and receiving circuit to transmit ultrasound waves to the target tissue which are focused at the focus position;
• receive ultrasound echoes from the region of interest to obtain echo information in the region of interest;
• and
• obtain a shear wave information corresponding to the region of interest according to the echo information obtained by the receiving control unit;
• and
• a display which displays an image generated by the processor.
