Microwave breast imaging requires a calibration process, which extracts the tumor response from the received signal. Existing calibration methods require more than two measurements. In this letter, we propose a calibration method called “in-place calibration” for time-domain microwave imaging. The method can obtain the received signal and the reference signal in a single measurement with the antenna...
Microwave imaging systems for breast cancer detection require calibration process to separate tumor response from measured data. In-place calibration can obtain the calibrated signal with a single measurement. We modeled 4 types of heterogeneous breast phantom. Microwave imaging was conducted using in-place calibration with heterogeneous breast phantoms. The tumor was found well with breasts which...
Microwave imaging systems for breast cancer detection go through calibration process to extract tumor response from measured data. All the calibration methods that have been proposed so far require multiple measurements. In this paper, we propose a novel calibration method that requires only single measurement. Simulation results with 3D hemispherical breast model show that the restored image is better...
