The present invention provides an ultrasound system, which comprises: a signal acquiring unit to transmit an ultrasound signal to an object and acquire an echo signal reflected from the object a signal processing unit to control TGC (Time Gain Compensation) and LGC (Lateral Gain Compensation) of the echo signal a TGC/LGC setup unit adapted to set TGC and LGC values based on TGC and LGC curves inputted by a user and an image producing unit adapted to produce an ultrasound image of the object based on the echo signal. The signal processing unit is further adapted to control the TGC and the LGC of the echo signal based on the TGC and LGC values set by the TGC/LGC setup unit.
