Robust Capon Beamformer with frequency Smoothing applied to medical ultrasound imaging

Long, Xian; Salehin, S.M.Akramus; Abhayapala, Thushara

Description

In recent years, Robust Capon Beamformer with Spatial Smoothing (RCB-SS) has improved ultrasound imaging. The RCB-SS is implemented in the time domain and spatial smoothing has the disadvantage of reducing the effective aperture leading to lower lateral resolution. In this paper, we propose a new adaptive beamformer in the frequency domain using frequency smoothing. We investigate the performance of our method using experimental data and compare its performance with RCB-SS and Delay and Sum...[Show more]
