Construction and testing of ultrasound broadband transducers for blood flow sensing.
Ultrasound pulsed transducers are very important for blood flow measurement and imaging. Ultrasound pulsed transducers are broadband transducers which require relatively heavy external damping to achieve a good axial resolution and an adequately wide bandwidth. In this work, using a simple RLC circuit model, broadband transducers were constructed and tested. The results are quite applicable for pulsed Doppler blood flow measurements.
