Researchers develop an inexpensive doppler ultrasound which detects veins accurately.
Michael Gray and his research team from Georgia Institute of Technology as developed a new doppler ultrasound which detects veins accurately. The researchers feels that locating veins accurately would avoid unnecessary punctures during injections which causes inflammation and infection.
The new technology gives a 3-D dimensional structure using doppler effect which uses an alternating wavelength and frequency which transmits acoustical waves which detects the moving blood between the stationary tissue sand skin. Compared to ultrasound vein detector which is very expensive this doppler ultrasound is a hand held instrument and is comparatively cheaper. The device emits a thin acoustical wave through the reflector which directs into the angle of the skin a beam of ultrasonic waves which detects the veins accurately through which the physician injects the needle parallel to the sound beam.
