Abstract:
|
A prototype imaging system for active microwave
tomography using cylindrical geometry has been developed,
making is possible to obtain images of the dielectric properties
of biological targets at 2.45 GHz. The system requires no mechanical movements to illuminate the body from multiple directions (views) and measure the scattered fields. In this way a
complete data set consisting in 64 views is acquired in 3 s using
low-power illumination. The system is described, including images obtained with biological phantoms and actual bodies. |
