Select a value between 0 and 3 by tapping Filter on the touch screen or using the dial-button.

This is an electric filter to remove the low-frequency doppler signals generated by the movement

of blood vessel walls. Adjust the Cutoff Frequency to remove doppler signals whose frequency is

lower than the cutoff frequency.

Scale (PRF)

Rotate the Scale dial-button on the touch screen. Rotating the Scale dial clockwise makes the PRF

(Pulse Repetition Frequency) increase so that the speed range of the blood flow is widened, and

vice versa.

■

BaseLine

Rotating the dial-button clockwise increases the Baseline.

In Color Doppler mode, the color bar indicates the direction and speed of blood flow. Based on the

Baseline at the middle, red indicates the direction and speed of blood flow toward the probe. By

contrast, blue indicates the direction and speed of blood flow that flows in the opposite direction

of the probe.
