1. An ultrasound imaging device, comprising:
- a signal converter to emit an ultrasonic signal to an object and receive the ultrasonic signal reflected from the object, and to convert the received ultrasonic signal into an in-phase/quadrature-phase (I/Q) signal corresponding to each pixel of an image in an ultrasonic image; and
a control unit to convert the I/Q signal into a frequency domain to compute a skewness, and to apply a clutter filtering to the I/Q signal according to the computed skewness.

Abstract
An ultrasound imaging device according to exemplary embodiments of the present invention may determine a skewness with respect to an in-phase/quadrature-phase (I/Q) signal in a frequency domain, and may provide a decision logic of a clutter filtering using the skewness. Accordingly, by filtering a clutter signal of the I/Q signal according to the skewness of the I/Q signal, an ultrasonic image may be formed using a signal in which a clutter component is filtered and/or submatrices in which a Doppler component is dominant, and the formed ultrasonic image may be provided to a user.
