Recently, minimum variance beamforming (MV BF) has been actively investigated as a method to improve the performance of an ultrasound system beamformer, especially in terms of both the lateral and contrast resolution. However, since the inverse spatial covariance matrix must be calculated, a severe problem with the method is the prohibitive computational complexity. Among numerous attempts to overcome...
This paper describes recently held research about combining two methods of autocorrelation based normal tissue Doppler imaging (TDI) and synthetic aperture imaging (SAI). Doppler shift estimator based on autocorrelation has been widely used to various commercial TDI system because of its simple structure, robustness, and low computation power requirements. And through application of SAI, spatial resolution,...
This paper presents a research for enhancing B-mode image quality using both of synthetic aperture imaging and tissue harmonic imaging in the medical ultrasound imaging. Synthetic aperture imaging has been actively researched until recently for improving spatial resolution and contrast resolution of the ultrasound image. Tissue harmonic imaging also has been actively researched with a similar purpose...
