摘要

For the brain tumor, early diagnosis and treatment are particularly important.Also the tumor detection and imaging technology with high accuracy isrequired. Thus, the forward high-precision symplectic finite-difference timedomain(SFDTD) algorithm is proposed to calculate the propagation characteristicsof ultrawide-band microwave signal in brain tissue with tumor. Using itsadvantages of high precision and numerical stability, the SFDTD algorithmcan provide a theoretical reference for antenna design and optimization in realbrain tumor imaging and detection system. Meanwhile, the inverse beam formingimaging algorithm is proposed to detect the location and size of the braintumor. The imaging results are compared with preset tumor position and sizeto prove the correctness of the SFDTD algorithm and the BF algorithm. As aresult, this article provides the theoretical reference for brain tumor detectionequipment with parameter design and imaging algorithm.
