Abstract

The magnetoacoustic tomography with magnetic induction (MAT-MI) is a noninvasive imaging method which can reflect the conductivity distribution of the imaging target, and has broad application in early diseases diagnosis. Most previous studies of MAT-MI ignored the transducer aperture. However, the collected signal waveform is directly determined by the transducer acquisition mode, which affects the reconstruction images. In this paper, we use the finite element simulation software COMSOL Multiphysics to build magnetoacoustic tomography models, the signal is firstly collected by the a finite aperture transducer, and the sound sources distribution images based on measurements are constructed with time reversal method.Then, we study the relationship between transducer aperture and reconstructed image resolution. The results show that the transducer location should be far away from the detected sample under the premise of acceptable sensitivity to reduce the influence of the transducer aperture on the image resolution, which can obtain high quality reconstructed images. Our study provides guidance for the construction of MAT-MI detection systems.
