Abstract
Ultrasound imaging methods are provided. The method includes: determining a region of interest in a target tissue; determining at least one ultrasound transducer group in an ultrasound probe and a focus position according to the region of interest in the target tissue; controlling, according to the determined focus position and the at least one ultrasound transducer group, transducers in the at least one ultrasound transducer group to transmit, to the target tissue, ultrasound waves that arrive at the corresponding focus point simultaneously, to form a sound field that completely covers the region of interest in the target tissue; and receiving ultrasound echoes of the ultrasound waves from the region of interest to obtain echo information in the region of interest.
Claims19
An ultrasound imaging method, comprising:
- determining a region of interest in a target tissue;
- determining at least one ultrasound transducer group in an ultrasound probe and a focus position according to the region of interest in the target tissue, wherein
- a depth of the focus position corresponding to the at least one ultrasound transducer group is greater than or less than a depth range of the region of interest, or
- a depth of the focus position corresponding to the at least one ultrasound transducer group is within a depth range of the region of interest and a width formed by all focus points corresponding to the at least one ultrasound transducer group and arranged along a lateral direction in the region of interest is greater than or equal to a width of the region of interest;
- controlling, according to the determined focus position and the at least one ultrasound transducer group, transducers in the at least one ultrasound transducer group to transmit, to the target tissue, ultrasound waves that arrive at the corresponding focus point simultaneously, to form a sound field that completely covers the region of interest in the target tissue;
- and
- receiving ultrasound echoes of the ultrasound waves from the region of interest to obtain echo information in the region of interest.
An ultrasound imaging method, comprising:
- generating a shear wave in a target tissue which propagates in a region of interest;
- determining at least one ultrasound transducer group in an ultrasound probe and a focus position according to the region of interest, such that a sound field generated by the at least one ultrasound transducer group completely covers the region of interest;

- receiving ultrasound echoes from the region of interest to obtain echo information;
- increasing a receiving density for the echo information in a lateral range in the region of interest;
- and
- obtaining a shear wave information corresponding to the region of interest according to the echo information with increased receiving density.
