Abstract

Recently, a method for focusing at all imaging points both in transmit and receive was proposed. This method uses transmit synthetic focusing and receive dynamic focusing in conventional B-mode ultrasound imaging systems. Transmit focusing is synthesized using the RF data of each scanline, together with all other relevant scanline data previously stored. Experimental results show that the proposed method improves lateral resolution and SNR of real-time B-mode images at all imaging depth points
