Breast cancer cases are increasing year by year and second leading reasons for the women's death worldwide. Early detection is very important and will help to save thousands of peoples' lives. The available systems such as Mammogram, MRI and ultrasound are invasive, expensive and need expert to operate. This paper presents a low cost and non-invasive breast cancer detection system for early detection...
Gaussian monocycle pulse propagations in breast phantoms were investigated for multi-static radar-based breast cancer detection. A 4 × 4 flat antenna array was placed on the breast phantom with a flat surface. To reconstruct confocal images of a cancer, waveforms with a tumor phantom were calculated by subtracting the reference signal from the measured waveforms. The reference signal was formed by...
A direct extraction method of tumor response based on ensemble empirical mode decomposition (EEMD) is proposed for early breast cancer detection by ultra-wide band (UWB) microwave imaging. With this approach, the image reconstruction for the tumor detection can be realized with only extracted signals from as-detected waveforms. The calibration process executed in the previous research for obtaining...
Ultra wide-band (UWB) microwave imaging technique is very promising in detecting the early breast cancer. In previous studies, the tumor-free model was always needed to help extract the calibration waveform, which cannot be obtained directly in the real clinical detection. In this paper, to solve this problem, a novel signal processing method based on ensemble empirical mode decomposition (EEMD) is...
Survival rate for breast cancer is directly related to the stage at diagnosis, therefore clinical emphasis is on early screening and detection. Microwave radiometry is a passive imaging modality proposed for breast cancer detection without the need for ionizing radiation. Detection of breast tumor using radiometry is challenging as the intensity of the thermal radiation received by the antenna is...
In this paper, we propose an UWB based multi static imaging technique which seeks to produce images and localize malignant breast tissues by processing the backscattered ultra-wideband (UWB) signals from numerical models of both tumor and normal breast tissues. We demonstrate that standard capon beamforming (SCB) combined with time-of-arrival (TOA) could give some reasonable results for imaging and...
