Ultra-wideband (UWB) antennas such as compact vivaldi antennas has been applied to the simulation experiment of breast cancer detection. A commercial-made synthetic breast phantom model is used in our experiment. We can find that it is effective to detect the breast cancer tumor using vegetable gelatin model subtraction method. Image reconstructions of the breast models using reflection data have...
Simulation experiment of breast cancer detection has been performed using an ultrashort-pulse radar with compact vivaldi antennas. A synthetic breast phantom and metallic balls or high-k dielectric cubes are used as tumor in our experiment. Image reconstructions of the breast models using reflection data will be presented. We measure reflection data in order to reconstruct images of the breast models...
In conclusion, the simulation study using FDTD method suggests that breast cancers with less than 1 cm can be detected by an image reconstruction technique named confocal microwave imaging. Preliminary experiments of an ultrashort-pulse radar confirm that the breast cancer detection is possible by using UWB antennas, such as log-spiral and bow-tie antennas. The additional data processing should be...
In recent years, pulsed microwave imaging in the gigahertz range has been suggested as a promising complementing methodology to the currently existing detection and imaging techniques. This technique is based on significant electrical contrast between the cancerous and healthy breast tissue in the microwave range. In this paper, we investigate tumor detection capabilities of the CPW-fed elliptical...
