混合模态人体个性化组织介电特性电磁模型的建立与应用研究
Research on the Establishment and Application of Subject-specific Dielectric Properties Electromagnetic Model Using Hybrid Imaging Modalities
摘要
Abstract
This paper aimed to explore the establishment of dielectric properties subject-specific electromagnetic model using hybrid imaging modalities and to provide necessary load model to analyze and calculate the distribution of electromagnetic fields in the tissues. Based on the computed tomography (CT) and magnetic resonance (MR) images, this paper established the subject-specific dielectric properties electromagnetic model named‘fusion’. Based on the CT images, this paper also established another model named ‘single’. By using the established models, electromagnetic simulations were implemented to obtain the distribution of the B1 field and SAR at 1.5 T and 3 T. By comparing the results of ‘fusion’ model and ‘single’ model, we can conclude that the subject-specific dielectric properties electromagnetic model using hybrid imaging modalitiesis capable of offering subtler results for predicting the B1 field and SAR distribution.关键词
