Abstract
Disclosed are an ultrasonic imaging system and method thereof. An ultrasonic probe is controlled to transmit ultrasonic waves to a region of interest at a plurality of steering angles respectively. Ultrasonic echoes are received to obtain the channel echo data. The channel echo data corresponding to at least part of the steering angles are beam-formed with the same receiving-line grid to obtain the beam-formed data.
Claims16
An ultrasonic imaging system, comprising:
- an ultrasonic probe having a plurality of array elements;
- a transmitting and receiving control circuit configured to control the ultrasonic probe to transmit ultrasonic waves to a region of interest and receive ultrasonic echoes of the transmitted ultrasonic waves, to obtain channel echo data;
- a processor configured to generate an ultrasonic image according to the channel echo data;
- and
- a display configured to display the ultrasonic image;
- wherein, the transmitting and receiving control circuit is configured to:
- control the ultrasonic probe to transmit the ultrasonic waves at a plurality of steering angles to the region of interest, respectively;
- and
- control the ultrasonic probe to receive the ultrasonic echoes of the ultrasonic waves transmitted at the plurality of steering angles, to obtain multiple groups of channel echo data, wherein each group of channel echo data is obtained by the ultrasonic echoes of the ultrasonic waves transmitted at one of the plurality of steering angles;
- and
- wherein, the processor is configured to:
- beam-form the multiple groups of channel echo data with a receiving-line grid comprising a plurality of grid points to obtain multiple groups of beam-formed data, wherein the multiple groups of channel echo data are beam-formed with a same receiving-line grid;
- and
- generate the ultrasonic image based on the multiple groups of beam-formed data.
An ultrasonic imaging method, comprising:
- transmitting, via an ultrasonic probe, ultrasonic waves at a plurality of steering angles to a region of interest, respectively;
- receiving, via the ultrasonic probe, ultrasonic echoes of the ultrasonic waves transmitted at the plurality of steering angles, to obtain multiple groups of channel echo data, wherein each group of channel echo data is obtained by the ultrasonic echoes of the ultrasonic waves transmitted at one of the plurality of steering angles;
