PURPOSE:To provide the ultrasonic wave diagnostic device having a color Doppler function and a zero shift function capable of checking more in details a blood flow in a reagent through the continuous change of a color tone of the blood flow at from its lowest speed up to a highest speed. CONSTITUTION:The device is provided with a display device 12 displaying a phenomenon of color Doppler, a probe 14 and a device main body 16 controlling the display device 12 in response to an output of the probe 14, and the device main body 16 includes a means 18 calculating a speed of a blood flow from an output of the probe 14, a means 20 moving a base line on a flow speed axis in a color scale according to an instruction inputted by the user, and a means 22 controlling a color and a color tone of the blood flow on a displayed picture through the use of the calculation result of the flow speed according to the characteristic in which the color tone is continuously increased or decreased from a lowest flow speed after the movement of the lowest blood speed point toward the tip of the color tone axis of the color scale. |
