This paper proposes efficient algorithms to enhance the nearfield electromagnetic imaging of human head. Forward problem is modeled using SAM head phantom with brain tumor anomalies, surrounded by a circular applicator antenna array. Scattered signals are compressively sensed (CS) at a limited number of sensing positions, and the sensed signals are preprocessed efficiently using a proposed novel technique to maximize information extraction. A dictionary is formed and then implemented in CS based inverse problem analysis. Reconstructed images are enhanced using new post-processing techniques to improve the spatial resolution. Image quality is analyzed using the quality metric in terms of peak signal-to-noise ratio (PSNR). The quality of the reconstructed images and the corresponding PSNR values reveals the validity of the imaging techniques.Index Terms-Nearfield imaging, electromagnetic imaging, head imaging, compressed sensing, SAM phantom.This full text paper was peer-reviewed at the direction of IEEE Instrumentation and Measurement Society prior to the acceptance and publication.978-1-4799-6477-2/15/$31.00 ©2015 IEEE

Gain of the conventional Vivaldi antenna (CVA) decreases at higher frequencies. A phase correcting lens (PCL) made up of nonresonant rectangular patch unit cells (UCs) is proposed to correct this problem. The layout of the UCs is specially designed taking into account the actual phase error at antenna aperture. The detailed analysis, design and discussion for the CVA with the proposed PCL are performed. The CVA, CVA with one‐layer PCL (CVA‐OPCL), and three‐layer PCL (CVA‐TPCL) are fabricated and measured. The measured results agree well with the simulated ones. The measured results show that the proposed CVA‐TPCL provides a gain variation of 5.75‐14.9 dBi in the wide operating range from 3.5 to 16 GHz, which leads to 1.1‐6.1 dBi gain enhancement than that of the CVA. In addition, the E‐plane half power beamwidths become narrowed significantly at higher frequencies. An average improvement of 4.54 dB is achieved in terms of the front‐to‐back ratio. The sidelobe levels, on average, are reduced by 4.1 dB and 2.8 dB for E‐plane and H‐plane, respectively.

“…The detection of a 5-mm diameter tumor was evaluated through a printed monopole antenna that scanned the phantom in a mono-static radar configuration. Measurements are processed through three different linear non-coherent detection techniques such as migration [5], Wide Band Multiple Signal Classification, MUSIC [6] and Interferometric MUSIC [7]. The resultant reconstructions are compared and evaluated in terms of Full-Width-Half-Maximum, FWHM, Signal-toClutter Ratio, SCR, Signal-to-Mean Ratio, SMR, and Spatial displacement, SD.…”

Abstract This paper presents a 2-D breast phantom which was realized with oil-in-gelatin materials for the evaluation of three different tumor detection methods operated in the microwave spectrum 1 -3 GHz. A planar monopole antenna was used to scan the phantom in a multi-monostatic configuration across 36 angular locations. Results show a better performance of an Interferometric-MUSIC approach when compared to Non-coherent Migration and Wide Band MUSIC.
