Vivid physical simulation model for electrical impedance scanning imaging of breast

Abstract

The invention discloses a vivid physical simulation model for electrical impedance scanning imaging of a breast. The vivid physical simulation model comprises a breast shape body-simulated structural layer, an exciting electrode substrate, a detection electrode array module, detection electrode substituting pieces and separated components such as a pectoralis major tissue simulated body, a breast tissue simulated body, a cancerization mass simulated body and a skin tissue simulated body, wherein the electrical impedance characteristic of each of the pectoralis major tissue simulated body, the breast tissue simulated body, the cancerization mass simulated body and the skin tissue simulated body is set according to electrical impedance characteristic parameters of active breast tissues. The vivid physical simulation model is designed according to the breast states during actual clinical detection with electrical impedance scanning of the breast, and the electrical impedance characteristic parameters of the simulated bodies are set according to active tissue parameters, so that simulation results can be more approximate to actually detected results. Besides, simulation conditions can be set flexibly, and an effective simulation tool for carrying out scientific research on electrical impedance scanning imaging of the breast in a deep-going way is provided.

technical field [0001] The invention relates to the field of bioelectrical impedance imaging research, in particular to a realistic physical simulation model used for mammary gland electrical impedance scanning imaging research. Background technique [0002] Breast electrical impedance scanning imaging technology is a new type of functional imaging technology developed in recent years, and it has the characteristics of non-invasive and radiation-free. Based on the biophysical characteristics of the significant difference between the electrical impedance of breast cancer tissue and normal tissue, breast electrical impedance scanning imaging technology uses flat-panel array electrodes to detect the surface of the breast, and obtains the reflection of the current difference between each unit by extracting the current difference.

AI Technical Summary

Problems solved by technology

Such a model has a simple structure and cannot simulate the deformation state of the breast during actual detection; at the same time, because it does not include the skin layer, it cannot simulate the contact impedance between the skin and the electrode during actual measurement; , the setting of its electrical impedance parameters is not set according to the measured electrical impedance parameter values ​​of living tissue; therefore, the limitations of the current simulation model will lead to large errors in the measurement and calculation of simulation simulations, which cannot meet the needs of in-depth research on breast electrical impedance scanning imaging simulation
