Simulation study and experiment of breast cancer detection using an ultrashort-pulse radar

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 necessary to obtain better images. Near future research includes the application of pulse compression technique to reflected waves for clear image formation. We also plan to perform the experiment using a breast phantom which has similar dielectric properties to actual breast tissue.
