Abstract
An ultrasonic blood flow imaging apparatus includes transmitter/receiver for transmitting drive pulses to an ultrasonic transducer, and receiving and converting an echo signal from the transducer into an image signal, a Doppler processing section for extracting a Doppler signal component from the echo signal, and blood flow information output section for obtaining the blood flow velocity from the Doppler signal component to provide blood flow velocity information. A color conversion section is provided which converts the blood flow information into a color signal containing a hue signal component representing a hue corresponding to the blood flow velocity. The color signal is displayed in the hue corresponding to the blood flow velocity.
