Innovative Acoustic Reflection Imaging Techniques And Application To Clinical Breast Tomography
… beam-formed, constant sound speed ray models for fast image reconstruction. However, these techniques are inadequate for the emerging new field of ultrasound tomography (UST). We present a new technique for reconstruction of reflection images from UST data. We have extended the planar Kirchhoff …

A High-Resolution Microscopic Electrical Impedance Imaging Modality: Scanning Impedance Imaging
… typically involve methods that either increase image resolution or image contrast. This study investigates the possibility of the resolution improvement for electrical impedance imaging using motion, and presents a novel high-resolution and calibrated impedance imaging method called Scanning …

Analytical Modeling of Waveguide-fed Metasurfaces for Microwave Imaging and Beamforming
… imaging systems. These systems are used to form images of buried objects, which is crucial in security screening and synthetic aperture radar (SAR). Traditionally, the hardware needed for many imaging techniques is cumbersome, including large arrays of antennas or bulky, moving parts. However, …
