“…The potential of UWB for breast cancer detection has been demonstrated with experiments on simple homogenous breast phantoms, where soy bean oil [3] and flour-oil-saline mixture [4] have been used to simulate breast tissue in UWB imaging experiments. Successful detection of tumor simulants of 4 mm and 10 mm diameter are reported in the respective experiments.…”

Abstract-The paper describes pulse-based ultra-wideband (UWB) radar microwave imaging experiments for breast cancer detection using breast phantoms with dielectric properties mimicking the human breast. Three homogeneous and seven heterogeneous breast phantoms are designed with a series of dielectric permittivity and variability and are used in tumor detection experiments. The experiments are conducted in time-domain with pulse generator and real-time oscilloscope.

“…The pulse generator is connected to a UWB transmitter antenna (3.1-10.6 GHz frequency range). A metallic rod that emulates the tumor, immersed in an oil-filled cylindrical glass tank is used as a phantom [26,27]. The skin is simulated using the cylindrical surface of the tank and the antennas are air coupled.…”

Abstract-This paper studies the potential of ultra-wideband (UWB) microwave imaging for detection and localization of breast cancer in its early stages. A method is proposed for locating tumors which is based on the time-of-flight of the signal backscattered at the tumor. Timeof-flight is detected using a wavelet transform algorithm. The main contribution of this paper is that it proposes to determine the position of the tumor by using an adapted version of the centroid localization method used in wireless sensor nodes. Its main advantage is that it does not require knowing a priori neither the propagation velocity of the breast nor its dielectric permittivity. The feasibility of the method has been investigated by means of simulated and experimental results with an ultra-wideband radar and a phantom.

“…An important application UWB technology is breast cancer detection through imaging [2,3]. Breast cancer is a very dangerous and deadly disease and an early detection of smaller tumors have a better chance of successful treatment [4]. Because of their wide bandwidth and high gain, tapered slot antennas (TSAs) have been utilized in breast cancer detection [5,6].…”

Abstract-A distortion-less ultra-wideband tapered slot antenna is designed to achieve wide band impedance matching and high gain without requiring coupling liquids. The antenna is embedded in a suitable dielectric material for compact size and performance improvement. The near-field test is simulated by placing several field probes near the antenna to plot the radiation pattern and polarization isolation. The antenna exhibits a highly directive pattern and polarization isolation in near field. The time domain antenna distortion is tested by calculating the fidelity and group delay. The results show low distortion and also show the importance of covering the antenna by dielectric layers for bandwidth increment and distortion reduction. To evaluate the antenna performance in breast cancer detection, three breast phantoms are imaged by using the raster scan imaging method. Two approaches are proposed to detect tumors without the need of breast background data. The approaches based on the effect of the tumor on transmission and reflection parameters on the frequency band allowed for medical applications. The obtained images show the antenna to be a strong candidate for breast imaging as well as in tumor detection for different scenarios that include complex multi-layer phantom and small tumor.
