Provided are an ultrasound system and a method for operating the ultrasound system, which may calculate a direction of an ultrasonic beam in real time and may adjust the ultrasonic beam based on the calculation result. The ultrasound system may include a probe to emit an ultrasonic beam to an object, a processor to measure a first reflection angle of the ultrasonic beam at a predetermined point in the object, a mapping table to map the measured first reflection angle to the predetermined point and to record mapping data, and a controller to determine an emission angle of the ultrasonic beam to the predetermined point based on the first reflection angle recorded in the mapping table, and to control the probe to emit the ultrasonic beam at the determined emission angle.
