Description

technical field [0001] This specification relates to the technical field of ultrasonic detection and diagnosis, in particular to an ultrasonic imaging method, device and computer-readable storage medium. Background technique [0002] Ultrasonic imaging is to transmit ultrasonic waves from an ultrasonic probe to an object to be inspected, and generate an ultrasonic image according to echo signals of the ultrasonic waves. Classified by beam type, ultrasonic beam types generally include focused waves and non-focused waves (such as plane waves, divergent waves, wide beams, etc.), and different beam types have their own advantages and disadvantages. For example, focused waves have high focusing energy, but using focused Waves are emitted more times during imaging; non-focused waves such as divergent waves and plane waves are suitable for higher frame rates but the focus energy is inferior to focused waves. The imaging speed is fast, the sound field is more uniform, but the image ...

Problems solved by technology

Classified by beam type, ultrasonic beam types generally include focused waves and non-focused waves (such as plane waves, divergent waves, wide beams, etc.), and different beam types have their own advantages and disadvantages. For example, focused waves have high focusing energy, but using focused There are many times when the wave is used for imaging; unfocused waves such as divergent waves and plane waves are suitable for higher frame rates but the focusing energy is inferior to that of focused waves. The imaging speed is fast and the sound field is relatively uniform but the image signal-to-noise ratio is low.

[0003]In the past ultrasonic imaging technology, focused waves were mostly used to emit concentrated waves in a certain area in order to improve the image quality of this area. However, although the traditional focused wave emission method has high energy, However, there are often cases where the frame rate optimization is limited due to the number of launches and the long launch time. At present, there are also cases where plane waves are used to supplement local launches in non-core areas (that is, areas outside the above-mentioned focused launch areas), but still Failure to fully integrate the respective advantages and disadvantages of different beam types, through reasonable planning and combination, in order to give full play to the respective advantages of multiple ultrasonic waves, improve the overall imaging efficiency, and better meet the imaging needs of users
