10 MHz Ultrasound Linear Array Design for Medical Application

This report represents a design and simulation of 10 MHz ultrasound transducer for medical application. The array is designed with 64 elements of 50µm width, 25µm kerf and 1mm elevation for each element. This results in the total transducer dimension of 1mm x 4.8mm. Piezoelectric material PZT 5H is chosen as the active layer while commercial materials named Ecosorb-MF116 and Polystyrene Fostarene-50 are chosen as two matching layers. Transducer’s 1D model using XTrans design toolbox and 3D FEM Comsol models (charge and voltage control) are investigated both accounted the effect of the 500nm electrode layers. Single element and array beam forming are calculated using Field II. A simulation of phantom imaging is observed using the transducer
