Optimizing Ultrasound Piezo-Disk Transducers Medical ultrasound imaging is vital for doctors and can be improved by using a smaller, more cost-effective machine COMSOL first proved the accuracy of simulation compared to experimentation, then changed the parameters to give a certain desired probe performance COMSOL News 2012: Spicci & Cati, R&D Department, Esaote S.P.A., Florence, Italy Experimental and model results are in good agreement, confirming the modeling technique. COMSOL model showing how the silicon lens allows the ultrasound beam to be steered or directed.
