PROBLEM TO BE SOLVED: To provide an ultrasonic Doppler diagnostic system capable of reducing an anticipation error in a defective Doppler signal in a segment scan and capable of improving both image qualities of a B (or B color) mode image and a Doppler image. SOLUTION: This ultrasonic Doppler diagnostic system practices a segment scan for alternately causing a Doppler segment period of actually generating a Doppler signal according to practice of a Doppler scan and a non-Doppler segment period of generating no Doppler signal according to nonpractice of the Doppler scan to anticipate the Doppler signal of the non-Doppler segment period by jointly using an AR modle using noise as internal input and an ARX model using a living body signal correlated to the Doppler signal as external decided input. |
