Abstract

The application provides a method and a device for ultrasonic imaging as well as ultrasonic imaging equipment. The method comprises the following steps: a control excitation component applies coded excitation of different frequencies to each array element in an ultrasonic probe, so as to enable each array element to utilize the applied coded excitation for producing and emitting ultrasonic signals; ultrasonic echo signals returned by the ultrasonic probe are received; the coded excitation applied to each array element is utilized for decoding the corresponding ultrasonic echo signals; and beam forming is carried out after the decoded ultrasonic echo signals are weighted, so as to obtain beam forming signals and display ultrasonic images according to the beam forming signals. Through the way of applying the coded excitation of different frequencies to each array element, the invention can increase the energy carried by the ultrasonic signals, promote the penetration force, enable the received ultrasonic echo signals not to interfere with each other and improve the image contrast. The image resolution is also improved by adopting the weighting method for beam forming.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to an ultrasound imaging method, device and ultrasound imaging equipment. Background technique [0002] In medical ultrasound imaging, beamforming is one of the core processing steps of ultrasound imaging. Usually, the ultrasonic probe in the ultrasonic imaging equipment sends ultrasonic signals through multiple array elements into the object under test, and then receives the ultrasonic echo signals reflected by the object under test through each array element, and transmits them back to the ultrasonic imaging equipment In the processor, the processor performs beamforming on the ultrasonic echo signals returned by each array element to obtain the beamforming signal, and performs ultrasonic image display according to the beamforming signal. [0003] In related technologies, the beamforming process usually adopts DAS (Delay And Sum, delay superposition) method and...
