Three-dimensional ultrasound matrix imaging

Nature Communications, 2023
Matrix imaging paves the way towards a next revolution in wave physics. Based on the response matrix recorded between a set of sensors, it enables an optimized compensation of aberration phenomena and multiple scattering events that usually drastically ...

Terahertz time-domain attenuated total reflection spectroscopy integrated with a microfluidic chip

Frontiers in Bioengineering and Biotechnology, 2023
The integration of a microfluidic chip into terahertz time-domain attenuated total reflection (THz TD-ATR) spectroscopy is highly demanded for the accurate measurement of aqueous samples.

Three-dimensional visualization as a tool for interpreting locomotion strategies in ophiuroids from the Devonian Hunsrück Slate [PDF]

Royal Society Open Science, 2020
Living brittle stars (Echinodermata: Ophiuroidea) employ a very different locomotion strategy to that of any other metazoan: five or more arms coordinate powerful strides for rapid movement across the ocean floor.

Three dimensional fluorescence imaging using multiple light-sheet microscopy. [PDF]

PLoS ONE, 2014
We developed a multiple light-sheet microscopy (MLSM) system capable of 3D fluorescence imaging. Employing spatial filter in the excitation arm of a SPIM system, we successfully generated multiple light-sheets. This improves upon the existing SPIM system

Three dimensional echocardiographic imaging of multiple recurrent myxomas

Monaldi Archives for Chest Disease, 2020
We report a case of a recurrence of 5 cardiac myxomas in both atria with atypical anatomical features difficult to image. Although a multimodality imaging was performed, three-dimensional echocardiography (3DE) was the only technique able to correctly ...

Checking the consistency of 3D geological models [PDF]

Geoscientific Model Development
Three-dimensional geological modelling algorithms can generate multiple models that fit various mathematical and geometrical constraints. The results, however, are often meaningless to geological experts if the models do not respect accepted geological ...

Three-Dimensional Printing: is it useful for Cardiac Surgery? [PDF]

Brazilian Journal of Cardiovascular Surgery, 2020
Introduction: The medical use of three-dimensional (3-D) images has been a topic in the literature since 1988, but 95% of papers on 3-D printing were published in the last six years.

Three dimensional (3D) imaging techniques in orthodontics-An update

Journal of Family Medicine and Primary Care, 2020
3D imaging is a technique which develops or creates the impression of depth within an image by deploying 2D data into 3-dimensional format. To aid in quality regulating processes for industrial purposes, 3D imaging has become an extremely valuable factor.

Optimizing Image Focus for Shape From Focus Through Locally Weighted Non-Parametric Regression

IEEE Access, 2019
Shape from focus is a passive optical technique that uses multiple images with different focus levels. To compute the sharpness of each pixel in the image sequence, obtained by translating the object plane at a constant step size along the optical axis ...
