Transmit apodization using a sinc function in an ultrasound system

An ultrasound system, comprising:

• a transmission unit configured to generate transmit pulse signals and apply weighting values based on a sinc function for transmit apodization to phase-shift transmit pulse signals corresponding to minus values of the sinc function by 180° and adjust amplitudes of the transmit pulse signals according to absolute values of the sinc function;
• a probe configured 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 configured to receive ultrasound echoes reflected from the target object;
• and
• a reception unit configured to form receive signals corresponding to a plurality of scan lines based on the ultrasound echoes.
