Kissinger, Dietmar Malignaggi, Andrea Ī 4-channel V-band beamformer featuring a switchless PALNA for scalable phased array systems.
The proposed method is shown to yield high quality reconstructions under heavy subsampling in the frequency and spatial domains.įranzese, Aniello Eissa, Mohamed Hussein Drenkhahn, Kevin E. Compressed sensing is employed to reduce the computational complexity of the reconstruction procedure by reducing data volumes directly at the measurement step, avoiding redundancy in the data and allowing the ability to steer the admissible computational effort at the expense of reconstruction quality.

Convergence problems of Neumann series in high contrast settings are addressed via Padé approximants. Multiple scattering is accounted for through the use of Neumann series. It comprises a physically motivated forward step and an imaging step that solves a suitable inverse problem. In this work, a two-step framework for Compressed UCT based on the integral approach to the solution of the Helmholtz equation is presented. In NDT, large speed of sound contrasts lead to strong artifacts if such phenomena are not modeled correctly however, enhanced models are computationally expensive. Ultrasound Computed Tomography (UCT) is challenging due to phenomena such as strong refraction, multiple scattering, and mode conversion.
