Single-FPGA 3D Ultrasound Beamformer

Jean-Philippe Thiran, Giovanni De Micheli, Federico Angiolini, Marcel Arditi, Aya Mohamed Naguib Ahmed Ibrahim, Ahmet Caner Yüzügüler

In medical diagnosis, ultrasound (US) imaging is one of the most common, safe, and powerful techniques. Volumetric (3D) US imaging, an emerging technique, is even more attractive than standard 2D imaging, as it allows for imaging without the local presence ...

Visualization of hepatic arteries with 3D ultrasound during intra-arterial therapies

Anaïs Laure Marie-Thérèse Badoual, François Michaud, Alexandre Bigot

Liver cancer represents the second most common cause of cancer-related mortality worldwide. The prognosis is poor with an overall mortality of 95%. Moreover, most hepatic tumors are unresectable due to their advanced stage at discovery or poor underlying l ...

Fluorescence and optical-resolution photoacoustic imaging through capillary waveguides

Demetri Psaltis, Christophe Moser, Salma Farahi, Nicolino Stasio, Emmanuel André Henri Bossy

Endoscopy can be used to obtain high-resolution images at large depths in biological tissues. Usually endoscopic devices have a diameter ranging from 1 to few millimeters. Using digital phase conjugation, it is possible to adapt ultrathin multimode fibers ...

A multi-purpose imaging endstation for high-resolution micrometer-scaled sub-second tomography

Goran Lovric, Marco Stampanoni

Time-resolved imaging of dynamic processes, ranging from biological in vivo studies to materials under in situ and in operando conditions, requires a flexible endstation capable of controlling complex components that interact in different configurations an ...

A sparse reconstruction framework for Fourier-based plane wave imaging

Jean-Philippe Thiran, Yves Wiaux, Rafael Eduardo Carrillo Rangel, Adrien Georges Jean Besson, Olivier Bernard

Ultrafast imaging based on plane-wave (PW) insonification is an active area of research due to its capability of reaching high frame rates. Among PW imaging methods, Fourier-based approaches have demonstrated to be competitive compared to traditional delay ...

Synergistic Coupling Between Electrochemical and Ultrasound Treatments for Organic Pollutant Degradation as a Function of the Electrode Material (IrO2 and BDD) and the Ultrasonic frequency (20 and 800 kHz)

César Pulgarin, Erika Herrera Calderon, Fernando Guzman Duque

Solutions of the organic pollutant model, Crystal Violet (CV), were subjected to ultrasonic, electrochemical treatment and its combination. Ultrasound was tested at two frequencies (20 kHz or 800 kHz) and 80 W in deionized water. After 120 min, 20 kHz cond ...

Ascending Aortic Aneurysm in Angiotensin II–Infused Mice: Formation, Progression, and the Role of Focal Dissections

Nikolaos Stergiopoulos, Lydia Aslanidou, Jessica Sordet, Bram Trachet, Alessandra Piersigilli, Patrick Segers

Objective To understand the anatomy and physiology of ascending aortic aneurysms in angiotensin II-infused ApoE(-/-) mice. Approach and Results We combined an extensive in vivo imaging protocol (high-frequency ultrasound and contrast-enhanced microcomputed ...

A 1D model of the arterial circulation in mice

Nikolaos Stergiopoulos, Lydia Aslanidou, Philippe Reymond, Bram Trachet, Patrick Segers

At a time of growing concern over the ethics of animal experimentation, mouse models are still an indispensable source of insight into the cardiovascular system and its most frequent pathologies. Nevertheless, reference data on the murine cardiovascular an ...

Three-dimensional echo planar imaging with controlled aliasing: A sequence for high temporal resolution functional MRI

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Mayur Narsude

Purpose In this work, we combine three-dimensional echo planar imaging (3D-EPI) with controlled aliasing to substantially increase temporal resolution in whole-brain functional MRI (fMRI) while minimizing geometry-factor (g-factor) losses. Theory and Metho ...
