摘要： The present invention relates to transmit apodization using a sinc function in an ultrasound system. The ultrasound system includes: a transmission unit operable to generate transmit pulse signals with transmit apodization applied by using a sinc function; a probe operable to generate ultrasound signals based on the transmit pulse signals to thereby form a transmit beam and transmit the transmit beam along a predetermined scan line among a plurality of scan lines in a target object, the probe being further operable to receive ultrasound echoes reflected from the target object; and a reception unit operable to form receive signals corresponding to a plurality of scan lines based on the ultrasound echoes.

摘要： A transmit/receive isolation for an ultrasound system to block a high voltage transmit signal from being propagated to a receiving unit during a transmission period of an ultrasound signal is disclosed. An ultrasound system includes a switching unit coupled to a transmitting unit, a ultrasound probe and a receiving unit. The switching unit includes diode bridges and a switching module having pairs of switches connected to the respective diode bridges, wherein each pair of switches is configured to perform switching between a plus voltage and a minus voltage to forward-bias a corresponding diode bridge to allow a respective receive signal to be propagated to the receiving unit in a first state and to reverse-bias the corresponding diode bridge to block a respective transmit signal to be propagated to the receiving unit in a second state.
