Abstract
A transducer (10) is controlled by a beam former (20) to transmit ultrasound pulses in multiple transmit focal zones (Z1-Z3) along at least two axes (A1 and A2). The beam former (20) causes the transducer (10) to transmit a first transmit pulse along one axis (A1) and to transmit a second transmit pulse along another axis (A2) before the echo pulse from the first transmit pulse is received by the transducer in order to decrease frame rates.
