One of the keys to medical microwave tomography is understanding the sensitivity of transmit-receive signals to changes in the electromagnetic properties to be reconstructed. This information is embedded in the Jacobian matrix for traditional inverse problem approaches and is a function of transmitter-receiver design characteristics and associated signal radiation/detection patterns. Previous efforts focused primarily on the 2D imaging problem for which sensitivity maps were generated in a single plane. In this paper, we describe sensitivity maps for the full 3D problem for monopole transceivers and their implications for associated antenna array configurations, including imaging zone coverage and computational efficiency.
医学微波断层扫描的关键之一在于理解发射 - 接收信号对待重建电磁特性变化的敏感度。该信息嵌入在传统反问题方法的雅可比矩阵中，并且是发射机 - 接收机设计特性以及相关信号辐射/检测模式的函数。先前的工作主要集中在二维成像问题上，在单个平面中生成敏感度图。在本文中，我们描述了单极收发器全三维问题的敏感度图及其对相关天线阵列配置的影响，包括成像区域覆盖和计算效率。
