This paper describes some methods of acceleration of the fast electromagnetic solver for the microwave imaging algorithm. This program is a part of a microwave tomography system, developed as a preclinical prototype for the early cancer detection, and operating in 3 – 6 GHz frequency band. The peculiarity of our algorithm is that it simulates all nearby objects of the breast under test, including...
This paper describes clinical trial and results of a microwave tomography system. This system was designed as a clinical trial prototype operating at 3GHz to 6GHz to detect woman-breast cancers. The subject numbers were 15 and it was non-blind test. Their images were reconstructed by the algorithm with a unique fast electromagnetic solver. Radiology doctors analyzed 30 images of 15 subjects and confirmed...
This paper describes a fast electromagnetic solver that allows to accelerate significantly the microwave imaging program, which produce reconstruction of permittivity and conductivity distribution of the breast under examination for purpose of early concern detection. The reconstruction algorithm is based on the solution of inverse electromagnetic scattering problem using iteration method, which applies...
In this work, we investigated dependence of the spatial resolution in a microwave tomography system on significant parameters such as an operating frequency, dielectric properties of testing material, number of testing antennas, diameter of the circular array, and total amount of measured data. The spatial resolution was calculated in 3 to 6 GHz, based on original estimation method in microwave imaging.
