微波断层扫描(MT)可以确定感兴趣体积的介电常数和电导率;已经表明,健康组织和恶性组织中的这些电特性之间存在对比,并且MT可以用于通过恢复它们的电特性值来辨别这些组织的介电对比图像。具有已知空间位置的对象的模拟和幻影实验已经表明,使用从成像体积中的内部结构导出的边界信息大大增加了恢复的属性值的准确性。在实践中,必须以足够高的分辨率来确定将用于重建组织的电特性图像的该空间信息,以分割感兴趣的边界区域和内部结构。本实验研究使用磁共振成像(MRI)在获得所需的空间信息中使用的网格生成的图像重建,并提供微波图像结果比较恢复与没有这种先验的空间信息的电性能。
Microwave Tomography (MT) can determine the permittivity and conductivity of a volume of interest; it has been shown that a contrast exists between these electrical properties in healthy and malignant tissues, and MT can be used to discern the dielectric contrast image of these tissues by recovering their electrical property values. Simulation and phantom experiments of objects with known spatial locations have shown that using boundary information derived from internal structures in the imaged volume greatly increases the accuracy of the recovered property values. In practice this spatial information, which will be used for reconstructing the tissue's electrical property images, must be determined with high enough resolution to segment boundary regions and internal structures of interest. This experiment investigates the use of Magnetic Resonant Imaging (MRI) in obtaining the desired spatial information used in mesh generation for image reconstruction and provides microwave image results comparing electrical properties recovered with and without this prior spatial information.
