A depth effect is observed where the optimal beamformer SOS for shallow depths is less than expected, approaching the expected values as depth approaches 1.5-2 times the physical aperture.Ultrasound data were obtained using a Siemens Antares machine (Siemens Medical Solutions USA Inc, Mountain view, CA) typically scanning imaging phantoms. Some of the initial work was done using an imaging research package fromanbsp;...
