ABSTRACT:
An ultrasound diagnostic apparatus having an ultrasound probe, a device for transmitting ultrasound to an subject through the ultrasound probe to receive echoes from the subject, a spectrum processor for approximating a spectrum of each of the echoes to a predetermined shape, and a unit for reconstructing an ultrasound image based on an output of the spectrum processor. The spectrums of the echoes are distorted by various reasons. There is a method for correcting a spectrum by enhancing only a high-frequency component of the echoes. Since this method is no more than to consider one reason, i.e., only frequency dependence of attenuation, a suitable correction cannot be made. According to the present invention, the spectrum is approximated to the predetermined shape, therefore the distortion of the spectrum caused by various reasons can be suitably corrected.
