Abstract: A method of generating an ultrasound image includes transmitting an ultrasound signal to a predetermined point included in an object and receiving at least three response signals reflected from the predetermined point; extracting a plurality of response signal pairs by combining the received at least three response signals two-by-two; obtaining a plurality of pieces of prediction vector information, each of the pieces of prediction vector information indicating a prediction velocity magnitude and a prediction velocity direction of the predetermined point, based on reception angles and Doppler frequencies of the response signals included in the plurality of response signal pairs; and determining vector information indicating a velocity magnitude and a velocity direction of the predetermined point, based on the plurality of pieces of prediction vector information.

Abstract: A method for obtaining an elastic feature of an object includes inducing a first shear wave in the object by transmitting a first push ultrasound signal which is generated by a probe of an ultrasound apparatus and a first grating lobe signal which relates to the first push ultrasound signal toward the object, transmitting a tracking ultrasound signal to an area of the object where the first shear wave has propagated, receiving, from the object, a reflection signal which relates to the tracking ultrasound signal, measuring a first shear wave parameter which indicates a shear wave characteristic of the first shear wave based on the reflection signal, and obtaining an elastic feature of the object by using the first shear wave parameter.

Abstract: An ultrasound system and a clutter filtering method thereof are provided. The clutter filtering method includes: transmitting an ultrasound signal to an object; receiving a reflection signal reflected from the object; performing a singular value decomposition (SVD) on a plurality of doppler signals constituting the reflection signal; dividing a representation of the object into a plurality of regions according to a result of performing the SVD; determining cutoff frequencies of the plurality of regions according to different methods; and performing clutter filtering on the plurality of regions by using the determined cutoff frequencies.
