Finding veins faster.(uses of ultrasound medical diagnostic equipment)(Brief article)

A team of researchers from Georgia Institute of Technology, Atlanta, is developing a handheld device that uses Doppler ultrasound technology to find veins quickly. As medics move the device along a patient's arm or leg, the transducer emits a thin acoustical beam which is directed into the patient's skin at a slight angle.

The device can determine the direction of the blood flow to distinguish arteries from veins, and once a vein is detected, an alarm is triggered, and medics insert the needle. More info: www.gatech.edu
