Abstract :
This paper proposes a new way for ultrasound color flow velocity estimation and display. This method sets up a mapping table which directly relates to the dynamic range of the velocity display by using an inverse mapping instead of calculating the arctangent value directly. This method is ideal for software implementation and offers an interactive way to user for changing the dynamic range of flow velocity to increase the display resolution
