Abstract

Accurate diagnostics of stenosis and blood flow distribution in carotid arteries requires transducers capable of producing 3D volume images with high frame rate for real time imaging. In the process of designing a matrix probe, an important goal is to realize the acoustic stack with high sensitivity and bandwidth. In this study, we employ a finite element analysis to evaluate the effect of sub-dicing on the performance of an acoustic stack in a piezoelectric matrix array. The array is integrated with an Application Specific Integrated Circuit (ASIC), which performs the task of signal amplification and efficient data reduction. The results show that two sub-dicing cuts can improve the sensitivity by 40%, bandwidth by 20%, and reduce the ringing time by 43%, which are all desired for improving the image quality.
