Numerical Simulation Based on Magnetoacoustic Tomography with Current Injection
Current injection magnetic-acoustic tomography combines the high resolution with conductivity tomography and high contrast with ultrasound imaging,which is a safe and non-invasive electrical impedance tomography technique.In the process of tumorigenesis,the changes in electrical characteristics of tumor are much earlier than the changes in the structure.Therefore magnetic-acoustic tomography has important significance for life science research and early diagnosis of the disease.In this paper,forward problem simulation study is carried out for the two-dimensional plane model.In the first,mathematical simulation model is established,and then the simulation model is verified.Finally,the influence of the scanning step and the signal-to-noise ratio on imaging quality is analyzed.The analysis shows that the forward problem proposed in this paper is a feasibility method for plane model,and the scanning step and the signal-to-noise ratio affect the imaging quality in a certain extent by analyzing the influence factors of imaging quality.
