We have previously introduced a k-space based 2D post-beamforming filter for restoring image contrast loss due to coarse sampling of the imaging apertures. The 2D regularized imaging operator was obtained and implemented on full frame data in k-space using computationally-efficient 2D fast Fourier transform (FFT). The computational efficiency of the 2D filter can be further improved by implementing...
A variety of imaging methods employing the principle of acoustic radiation force (ARF) have been proposed recently. It is now well accepted that ARF-based methods produce significant improvement in contrast compared to coventional ultrasound. However, interpretation of the ARF-induced displacements is rendered difficult in the presence of nearby boundary conditions, e.g. skin imaging. We present a...
