Abstract
An ultrasonic diagnostic imaging system is provided with synthesized transmit focus. Several beams are transmitted, each with a different transmit focus. Echoes received from the differently focused beams are combined to form a scanline with an extended focus. The echoes are preferably weighted and/or phase adjusted prior to being combined. Combining is performed in the r.f. domain before nonlinear processing of the signals such as amplitude detection. The resultant extended focus scanline exhibits the property of dynamic transmit focusing.
