| Popis: |
This chapter documents the hardware specifications of a prototype resonant chamber microwave tomography system that is currently under development for biomedical applications. The electromagnetic fields are generated and measured using a vector network analyzer. Details of the calibration procedure necessary to provide accurate information on the incident fields inside the imaging region and the scattered fields at observation points within the chamber are presented. The calibration procedure is based on an electromagnetic analysis of a detailed numerical model using the finite-volume time-domain (FVTD) technique. Images of dielectric profiles of simple objects using synthetic data obtained using idealized 2-D and 3-D FVTD models are provided using two inversion algorithms: DBIM and MR-CSI. |
