This research study was carried out to see the effect of diseased Popliteal arteries on the type of waveforms, so produced as a result of received echoes, during the Ultrasound procedure. The effect of diseased Popliteal arteries on the Ultrasonic waves was observed during the Ultrasound. The method targeted to find any change in the complete triphasic shape of waveform. 10 cases of diseased Popliteal arteries were observed by this method. The Result was the production of monophasic shape of waveform with little or prolonged portion of diastole on ultrasound image. This does not normally happens in the case of healthy Popliteal arteries. It is been concluded the formation of monophasic waveform with some portions of little or prolonged diastoles during the Ultrasound procedure is a clear and good symbol of diseased Popliteal artery.
