PROBLEM TO BE SOLVED: To achieve a higher diagnostic efficiency for the infarction of a blood vessel or the like with higher visual recognizability especially at the peripheral part of a CFM image by improving picture degradation of a color flow mapping(CFM) image attributed to error of interpolation computation of data. SOLUTION: This ultrasonic diagnostic system is provided with an ultrasonic probe 1, a transmitting/receiving unit 2 which obtains kinematic state information containing speed information of a fluid in vivo by Doppler scanning of an ultrasonic beam UB from the ultrasonic probe 1 and a color unit 3. The ultrasonic diagnostic system is also provided with a control part 10, a space interpolation processing part 11, an FM12, an H-way interpolation processing part 14 and the like at a DSC4. A pixel data of a CFM image is computed down to the accuracy of below desimal point from an N-bit blood-stream data (speed information) and is converted to an N'-bet bloodstream code (display code) containing the accuracy of below the desimal point. The bloodstream code is displayed on a color monitor 6 as CFM image through a luminance conversion unit 5. |
