Abstract
Description
technical field
[0001] The invention relates to the technical field of ultrasonic imaging, in particular to an adaptive ultrasonic beam synthesis method and system based on channel data. Background technique
[0002] In the medical ultrasound imaging system, from the ultrasound probe to the final display of the image, it must go through the transmission and reception circuit, analog signal to digital signal conversion, beam synthesis, signal baseband processing, digital scan converter and image post-processing and other links. Among them, the beamforming quality of the ultrasound imaging system has a crucial impact on the final imaging effect. The main processing methods of beamforming channel data include traditional hardware beamforming and software beamforming emerging with the development of general-purpose processor capabilities. The related technologies involved include electronic focusing and scan line control, apodization, variable aperture, etc. Whether it is hardw...
