the baseline in the middle, the red color indicates the direction and speed of blood owing toward

the probe. Conversely, the blue color indicates the direction and speed of blood owing away from

the probe.

C Mode Menu

Following items are displayed on menu when you press the Menu dial-button in C mode. Select the

item and adjust the value with the Menu dial-button.

■

Balance

Adjusts the range of the color image displayed by comparing the gray level of the 2D image with

the Doppler signal value of the color image. If the Balance value increases, the color image is seen

even where the 2D image signal is strong (bright), thereby increasing the color image range.

Select a value between 1 - 16 with the Menu dial-button.

■

Sensitivity

Set the sensitivity of the color image. Increasing the value enhances the color image, but reduces

the frame rate. Select a value between 8 - 31 with the Menu dial-button.
