“…Recently, Smith et al [40][41][42][43] proposed a near-field indirect HMI method, which involves recording the holographic intensity pattern and reconstructing the image by using Fourier transformation from the recorded intensity pattern. Compared to TSAR, indirect HMI has the ability to produce real-time image at a significantly low cost.…”

Electromagnetic waves at microwave frequencies allow penetration into many optically non-transparent mediums such as biological tissues. Over the past 30 years, researchers have extensively investigated microwave imaging (MI) approaches including imaging algorithms, measurement systems and applications in biomedical fields, such as breast tumor detection, brain stroke detection, heart imaging and bone imaging. Successful clinical trials of MI for breast imaging brought worldwide excitation, and this achievement further confirmed that the MI has potential to become a low-risk and cost-effective alternative to existing medical imaging tools such as X-ray mammography for early breast cancer detection. This chapter offers comprehensive descriptions of the most important MI approaches for early breast cancer detection, including reconstruction procedures and measurement systems as well as apparatus.

In this work, a compact indirect microwave holographic setup is proposed and developed by utilizing the low cost, specifically designed directive antennae as transmitter and receiver. Microwave holograms are recorded while scanning the 2D plane using (x-y) motorized translation stage. The recorded holograms are then reconstructed numerically employing the angular spectrum diffraction phenomenon. The quality of the reconstructed amplitude image is further enhanced through the deep neural network, in order to combat with the low resolution of reconstructed images. The quantitative and qualitative results exploit the possibility of developing the miniaturized indirect microwave holographic system for near field applications.

“…While tomography-based microwave imaging (TBMI) forms the dielectric scattering map of the breast, radar-based microwave imaging (RBMI) makes use of amplitude differences in the scattering signal and provides simple and powerful reconstructed amplitude-based images of the interested region. There are various numerical studies in the literature on diagnosis, detection and imaging of breast cancer with the use of microwave imaging such as circular [21] and indirect holographic reconstruction [22], confocal microwave imaging [13], multistatic adaptive microwave imaging [11], field mapping algorithm [23], hybrid reconstruction [24] and delay and sum procedures with various alternatives [8,25]. In [21], fibroglangular tissue structures mimicking the real breast tissues are used in a rotating platform filled with impedance matching liquid, and the scattering waves acquired with the help of Vivaldi antennas are processed with the holographical imaging method.…”

In this study, the scattering map of the breast is reconstructed by applying the matchingpursuit algorithm (MPA) to the simulation data obtained by the monostatic inverse synthetic aperture radar (ISAR) principle, and the locations of the tumors are determined by considering the peaks on the scattering map. The MPA iteratively searches the true solution by assuming every discrete point in the solution space to be a scattering center by dividing the imaging region onto a discrete grid. In order to obtain images with better resolution, the fine granularity of the grid for accurate solutions is provided at the expense of increased processing times. First, our approach based on MPA is tested on simulated data generated by MATLAB for breast tumor detection and imaging. Perfect reconstruction for the locations of the hypothetical breast tumor points is attained. Then, a full-wave electromagnetic simulation software named CST Microwave Studio (CST MWS) is used to generate backscattered electric field data from a constructed scenario in which a tumor is located in a breast model. Next, we use the collected data from the defined scenarios as an input to our algorithm. Resultant images provide successful detection and imaging of the tumor region within the breast model. The accuracy of the MATLAB and the CST MWS simulation results demonstrate the availability of our MPA-based focusing algorithm to be used effectively in medical imaging.
