An ultrasound system includes a probe scanning a target object by transmitting ultrasound signals and receiving ultrasound echo signals, a processor forming an ultrasound image based on the ultrasound echo signals and an ultrasound beam direction marker indicating a transmission direction of the ultrasound signals, and a display displaying the ultrasound image and the ultrasound beam direction marker. The processor controls the display such that the display displays a first indicator indicating a reference point of the ultrasound beam direction marker at a side of the ultrasound beam direction marker, and a second indicator indicating a location corresponding to the first indicator at a side of the ultrasound image.
