Scan Converter, Ultrasound Diagnostic Apparatus and Method capable of Real-Time Interpolation without Directional Distortion

The scan converter is real-time interpolation is possible without distortion of the orientation, the ultrasonic diagnostic apparatus and method is disclosed. According to an embodiment of the invention, C- mode vector interpolation, weighted according to the distance using four complex signal from the surrounding (Color flow-mode) (Vector interpolation) by distortion of the orientation of the speed information (Velocity data) this not occur, and this has the effect of creating a look-up table for vector interpolation (lookup table) to allow for real-time implementation of the scan conversion (scan conversion).
