Adaptive Models for Multi-Covariate Imaging of Sub-Resolution Targets (MIST).

Journal Article IEEE transactions on ultrasonics, ferroelectrics, and frequency control · July 2022 Multi-covariate imaging of sub-resolution targets (MIST) is a statistical, model-based image formation technique that smooths speckles and reduces clutter. MIST decomposes the measured covariance of the element signals into modeled contributions from mainl ... Full text Cite

Intrinsic Tradeoffs in Multi-Covariate Imaging of Sub-Resolution Targets.

Journal Article IEEE transactions on ultrasonics, ferroelectrics, and frequency control · October 2020 Multi-covariate Imaging of Sub-resolution Targets (MIST) is an estimation-based method of imaging the statistics of diffuse scattering targets. MIST estimates the contributions of a set of covariance models to the echo data covariance matrix. Models are de ... Full text Cite

Synthetic Aperture Focusing for Multi-Covariate Imaging of Sub-Resolution Targets.

Journal Article IEEE transactions on ultrasonics, ferroelectrics, and frequency control · June 2020 Coherence-based imaging methods suffer from reduced image quality outside the depth of field for focused ultrasound transmissions. Synthetic aperture methods can extend the depth of field by coherently compounding time-delayed echo data from multiple trans ... Full text Cite
