The analysis of blood flow patterns is of great importance in assessing Cardiovascular disease. Flow meters are also vital in the detection and diagnosis of COPD (Chronic Obstructive Pulmonary Disease) which are diseases affecting the respiratory system, such as: Asthma, Bronchitis, Lung Cancer, Emphysema.
The Ultrasonic Doppler FlowMeter is a University of Connecticut sponsored senior design project. The goal of the project is to create a 2 MHz signal transmitted via the help of a dual-element transducer from Panametrics, Inc. (a GE company).This signal should analyze the bloodflow in the cardiovascular system with the well established concept of the doppler effect. The signal received from the transducer will be amplified and mixed with the original to have an audible output generated through a loudspeaker.
The transducer is placed at a 45 degree angle to the blood vessel in order to produce the optimal (audible) frequency. The signal will be transmitted against the bloodflow, rather than with the bloodflow, in order to produce a louder sound.
