Abstract: For ring-array ultrasound tomography, two-dimensional frequency-domain full waveform inversion is the clinical gold standard for high-resolution imaging of the breast. While yielding ...

Abstract: This paper presents a 3D metal-only waveguide-based phoenix cell. The proposed cell uses open-ended waveguides, which allow a portion of the incident wave to pass through the phoenix cell.

Ultrasound tomography (UST) is a medical imaging system that uses the transmission of ultrasound through tissue to create images of the speed of sound. Currently, UST is based on a single-row ...
