Paper Abstract

This paper describes the method of using the finite-element analysis software, PZFlex, to direct the design of a novel ultrasound imaging system which uses conformal transducer arrays. Current challenges in ultrasound array technology, including 2D array processing, have motivated exploration into new data acquisition and reconstruction techniques. Ultimately, these efforts encourage a broader examination of the processes used to effectively validate new array configurations and image formation procedures. Commercial software available today is capable of efficiently and accurately modeling detailed operational aspects of customized arrays. Combining quality simulated data with prototyped reconstruction techniques presents a valuable tool for testing novel schemes before committing more costly resources. To investigate this practice, we modeled three 1D ultrasound arrays operating multistatically instead of by the conventional phased-array approach. They are: a simple linear array, a half-circle array with 180-degree coverage, and a full circular array for inward imaging. We present the process used to create unique array models in PZFlex, simulate operation and obtain data, and subsequently generate images by inputting data into a reconstruction algorithm in MATLAB. Further discussion describes the tested reconstruction algorithm and includes resulting images.
