There are provided embodiments for measuring an inclination angle of an ultrasound probe to correct a Doppler angle in real time. In one embodiment, by way of non-limiting example, an ultrasound system comprises: an inclination measuring unit configured to measure an inclination angle of an ultrasound probe at a predetermined cycle to form measuring information including the inclination angle, wherein the inclination measuring unit is mounted inside or outside of the ultrasound probe and a processing unit configured to calculate a Doppler angle correction value corresponding to the inclination angle based on the measuring information and calculate a corrected Doppler angle based on the Doppler angle correction value.
