摘要: Several adaptive beamforming imagers have been proposed to improve the spatial resolution of medical ultrasound imaging. These employ averaging technique and diagonal loading suppress correlated interferences acquire robustness, respectively. In this study, we propose that selects optimum size for with respect measurement depth. We a small factor −40 dB avoid deterioration in image quality. simulation method succeeded quality compared conventional beamspace Capon method. The sidelobe level −6 beam width were −26 0.27 mm, respectively, where those −16 0.40 depict higher than
