A digital scan converter (DSC) in an ultrasonic system stores a received ultrasonic signal and displays the ultrasonic signal via a display. The DSC calculates pixel data at a corresponding pixel point via an interpolation process using ultrasonic image data at sampling point which is positioned on two scan lines neighboring to the pixel point for displaying and has the same radius from a probe as that of the pixel point for displaying. Thus, a positional error does not exist on a rectangular coordinate system, and thus a picture quality is enhanced by eliminating artifact.
