Abstract
Current-responsive light-emitting diodes of different colors are provided adjacent to the tip of the hand-held transducer probe of a medical Doppler device. Mechanism is provided to actuate the diodes of one color when the direction of internal body matter detected by the Doppler device is toward the probe and to actuate lights of a different color when the direction of detected internal body matter is away from the probe. In addition, power supply to the diodes is controlled so that increasing brightness indicates increasing velocity of the detected internal body matter.
