微波成像的算法研究(英文)

A Study of Image Reconstruction Algorithm for Microwave Imaging

讨论了微波成像的原理及其在医学成像等领域的应用；针对目前微波成像的优点和不足，在傅里叶衍射成像定理的基础上，提出了算法设计，并由此实现了某特定介电常数的圆柱体图像重构．

The importance and basic principles of the microwave imaging applied not only in medical imaging, but also in underwater and seismic mapping,were presented. The computer simulation based on the Fourier diffraction projection theorem, was conducted on a cylinder with the solution provided by H Jack to calculate the scattered field at any point outside the cylinder. The reconstructed image of the cylinder of radius 3λ , relative dielectric constant 1.001, was plotted. To reduce the programming workloads and pay more attentions to the study of the algorithm, MathCad 6.0 was used for the computation.
