文摘

F-DMAS beamforming performance with Synthetic Aperture Focusing (SAF) is analyzed. Both Synthetic Transmit Aperture (STA) and monostatic SAF techniques are tested. Results of simulations, experimental phantom and in vivo scans are presented. Images show that with F-DMAS and STA a higher quality is achieved at all depths. Good results can be also obtained with simple monostatic SAF and F-DMAS.
