Cerebral Small Vessel Disease in Immune‐Mediated Thrombotic Thrombocytopenic Purpura Patients During the Acute Phase and Disease Remission

American Journal of Hematology, EarlyView.
ABSTRACT Immune‐mediated thrombotic thrombocytopenic purpura (iTTP) is a life‐threatening thrombotic microangiopathy characterized by acute neurological manifestations and long‐term sequelae related to microvascular brain injury. Cerebral small vessel disease (cSVD), detectable on MRI through lacunes, microbleeds, white matter hyperintensities, and ...

Research of total-focusing-imaging based on phase coherence and dB amplitude enhancement

AIP Advances
To address the issue of weak defect visualization in the ultrasonic total-focusing method (TFM) after denoising, this paper integrates Phase Coherence Imaging (PCI) and dB amplitude enhancement (dB) with the TFM.

The effect of ultrasound wave path estimation to defect characterization capability in half-skip total focusing method

Research and Review Journal of Nondestructive Testing, 2023
The total focusing method (TFM) is a post-processing imaging technique applied on full matrix capture (FMC) ultrasonic inspection (UT) dataset. In TFM the ultrasonic wave energy is synthetically focused on every pixel in the image region of interest ...

Low‐Field MRI as a Multiparametric Tool for Large Engineered Tissue Characterization

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Advances in 3D bioprinting have enabled the fabrication of large and complex engineered tissues, but their increasing size demands non‐invasive tools for monitoring structure, maturation, and perfusion. Magnetic Resonance Imaging (MRI) offers unique multiparametric capabilities, yet high‐field systems remain costly and inaccessible for most ...

Comparison of modelling approaches for liquid fluidized beds

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

Uncertainty-aware traction force microscopy.

PLoS Computational Biology
Traction Force Microscopy (TFM) is a versatile tool to quantify cell-exerted forces by imaging and tracking fiduciary markers embedded in elastic substrates. The computations involved in TFM are often ill-conditioned, and data smoothing or regularization

Apports de la TFMi par rapport à la TFM

e-Journal of Nondestructive Testing, 2023
L’un des paramètres importants quand on utilise le TFM pour reconstruire une image est le choix du, ou des, modes de reconstruction. Le choix est intuitif pour une inspection en ondes Longitudinales à 0°, type recherche de corrosion : pas de conversion ...
