Adjusting the Pulse Repetition Frequency (PRF) Scale and Color Box

Adjusting the PRF scale and color box

• Use the smallest color box required; when 2D imaging is combined with other modalities, e.g., color Doppler, the frame rate will drop. The best way to maintain frame rate is to decrease the 2D sector width.
• Adjust PRF color scale.
• The velocity scale may not automatically adjust as the color box is moved to different depths.
