Abstract

An ultrasonic beamforming method is provided. The ultrasonic beamforming method includes dividing an input ultrasonic signal into a plurality of regions in an observation space, calculating a weight value for each of the plurality of regions, calculating a pixel weight value for each pixel using the weight value for each region, and calculating a beamforming value using the pixel weight value.

Description

technical field [0001] The present disclosure relates to an ultrasound imaging system, and more particularly, to a high-definition ultrasound beamforming technology. Background technique [0002] Ultrasound images are used to analyze properties of tissue by outputting pulses and receiving reflected signals of the pulses. An ultrasound imaging system needs to be focused in order to obtain the reflective properties of tissue at a desired location. In delay-and-addition (DAS) processing, an ultrasound imaging system generates data from signals input to an ultrasound transducer during focusing. [0003] Accurate focusing on tissue at a desired location is difficult due to differences in signal velocity between adjacent tissues or refraction and reflection effects. In order to solve this problem, an adaptive weight beamforming technique has been proposed in which DAS processing is performed by giving weight to a signal input to each element of the ultrasonic transducer. Adapti...
