Embodiment Construction

[0072] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0073] Traditional ultrasound imaging generally uses transmit focusing, and then performs beamforming on the received echo signals after delayed and superimposed processing to obtain ultrasound images. The specific imaging process is to divide the image area into lines one by one, and then analyze the echo signal according to the time offset of the target point to obtain the data on each line. In order to ensure the image quality, the number of lines must be increased. In this way, the number of shots of the array element also increases, which eventually leads to a lower f...

Abstract

The invention relates to an ultrasonic imaging method, device and system and a storage medium. The method comprises the following steps: acquiring the total array element number and array element directivity angle of the ultrasonic probe; dynamically determining the size of an emission aperture when the ultrasonic waves are emitted every time according to the total array element number and the array element directivity angle within a preset emission frequency; the sizes of transmitting apertures are different when the ultrasonic waves are transmitted each time; transmitting ultrasonic waves to a target based on the sizes of the transmitting apertures, and receiving echo signals after the ultrasonic waves transmitted each time are reflected on the target; and performing beam forming on each echo signal to obtain an ultrasonic image of the target. By adopting the method, the imaging speed and the imaging quality can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an ultrasonic imaging method, device, system and storage medium. Background technique [0002] Ultrasound imaging is widely used in clinical diagnosis due to its non-invasive and ability to create real-time images. Among them, ultrasound imaging refers to the use of ultrasound beams to scan the human body, and by receiving and processing the reflected signals of the human body, images of the internal organs of the human body can be finally obtained. [0003] In the traditional technology, when ultrasonic imaging is used to obtain images of the human body, the image acquisition process is a process of continuously adjusting the ultrasonic imaging. Among them, when adjusting ultrasound imaging, if the image at a certain position is dark, then it is necessary to adjust the position of the focus to increase the brightness of the image at this position; or if the differen...
