Full waveform inversion for arterial viscoelasticity. [PDF]

open access: yesPhys Med Biol, 2023
Abstract Objective . Arterial viscosity is emerging as an important biomarker, in addition to the widely used arterial elasticity. This paper presents an approach to estimate arterial viscoelasticity using shear wave elastography (SWE). Approach .

Gaussian decomposition method for full waveform data of LiDAR base on neural network [PDF]

open access: yesScientific Reports
The full waveform data from airborne LiDAR (Light Detection and Ranging) provides information on the distance of the target. Accurately extracting the ranging information from the full waveform data is crucial for generating point clouds.

Accelerated Full Waveform Inversion by Deep Compressed Learning [PDF]

open access: yesSensors
We propose and test a method to reduce the dimensionality of Full Waveform Inversion (FWI) inputs as a computational cost mitigation approach. Given modern seismic acquisition systems, the data (as an input for FWI) required for an industrial-strength ...

Full-waveform inversion imaging of the human brain [PDF]

open access: yesnpj Digital Medicine, 2020
Magnetic resonance imaging and X-ray computed tomography provide the two principal methods available for imaging the brain at high spatial resolution, but these methods are not easily portable and cannot be applied safely to all patients.

Variational full-waveform inversion [PDF]

open access: yesGeophysical Journal International, 2020
SUMMARY Seismic full-waveform inversion (FWI) can produce high-resolution images of the Earth’s subsurface. Since full-waveform modelling is significantly nonlinear with respect to velocities, Monte Carlo methods have been used to assess image uncertainties.

Analyzing the Impact of Different Filtering Methods on Satellite Altimetry Full Waveform Decomposition [PDF]

open access: yesEPJ Web of Conferences, 2020
Filtering is an essential step in the denoising of satellite altimetry full waveform data, since any deformation and distortion in the shape of the waveform can cause errors in range estimation and further waveform decomposition will also be adversely ...

Randomized Source Sketching for Full Waveform Inversion [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
Partial differential equation (PDE) constrained optimization problems such as seismic full waveform inversion (FWI) frequently arise in the geoscience and related fields. For such problems, many observations are usually gathered by multiple sources, which form the right-hand-sides of the PDE constraint.
