Patent ID: 8679021

Claim:
An ultrasonic diagnostic apparatus to perform a global aliasing corrections comprising: a data acquisition unit configured to acquire phase signals as Doppler data from a moving object within an object by transmitting and receiving ultrasonic waves to and from the object; a correction unit configured to perform global aliasing correction processing of the phase signals acquired from the object based on a continuity in a two-dimensionally phase change, the global aliasing correction processing applied to an entirety of a predetermined two-dimensional space as a whole; and a display unit configured to display phase signals after the aliasing correction processing, wherein the correction unit performs the global aliasing correction processing with a weighted least squares method so as to minimize a square error between signals derived by wrapping gradients in a two-dimensional distribution of the phase signals acquired from the object and gradients in a two-dimensional distribution of phase signals after the global aliasing correction processing with using weights determined according to at least one of power signals of the moving object, dispersion signals of the moving object, velocity signals of the moving object, or gradients of the phase signals acquired from the object.
