Machine Learning for Automated Hepatic Fat Quantification

Sagreiya H., Akhbardeh A., Durot I., Rubin D.L., University of Pennsylvania, US

Nonalcoholic fatty liver disease is a global pandemic. This study investigated whether ultrasound point shear wave elastography measurements could predict hepatic fat quantification using a machine larning (ML) algorithm trained with fat quantification on MRI. [...]

Display Compatible pMUT Device for Mid Air Ultrasound Gesture Recognition

Huang C.H., Demi L., Mao S., Jeong Y., Cheyns D., Rottenberg X., Rochus V., IMEC, BE

1. BACKGROUND Recently, piezoelectric micromachined ultrasound transducers (pMUT) have proved their potential to make a reliable 2D ultrasound array. As shown in Fig. 1, the displacement of piezoelectric material layer is galvanised by electrical signals/acoustic [...]

A New Sonochemical Synthesis Route for Silicon Nanoparticle Inks for Energy and Nanomedical Applications

Cádiz Bedini A.P., Chen C., Klingebiel B., Notten P.H.L., Rau U., Forschungszentrum Jülich, DE

Silicon nanoparticles (Si-NPs) have become increasingly relevant in several important fields ranging from solar cells, next-generation quantum dot LEDs, lithium-ion batteries, and because silicon is biodegradable, their use as drug carriers or fluorescent markers has [...]

Ultrasound absorption in magnetic nanofluids

Sokolov V.V., Nadvoretskiy V.V., Moscow State University of Instrument Engineering and Computer Science, RU

Mechanisms of ultrasound absorption in magnetic nanofluids at the absence of external magnetic field are theoretically studied in the first part of the paper. The novel magnetodynamic mechanism of ultrasound absorption is introduced – it [...]

Micromachined Ultrasound Integrated Circuit

Hajati A., Latev D., Fujifilm Dimatix Inc, US

we present the design and experimental acoustic test data for an ultrasound transducer technology based on a combination of micromachined dome-shaped piezoelectric resonators arranged in a flexible architecture. Our high performance niobium-doped lead zirconate titanate [...]

Innovative Use of Ultrasound in the Production of High-Performance Coatings

Hielscher K., Hielscher Ultrasonics GmbH, DE

The metal oxide nanoparticles include nano-sized zinc oxide, titanium oxide, iron oxide, zirconium oxide and cerium oxide, as well as mixed metal compounds, such as indium tin oxide, zirconium and titanium. For the color, paint [...]

Disinfection of Cryptosporidium Parvum Oocysts in Water using Ultrasonic Treatment

Olvera M.E., Ilangovan K., Instituto Tecnologico y de Estudios Superiores de Monterrey, MX

Ultrasound in a liquid phase cause mass and heat transfer across the liquid through cavitational processes which act as nanoreactors to generate unstable mechanical equilibrium. The effect of 1 MHz ultrasound on the inactivation of [...]

Temperature Sensitive Liposomes for Local Drug delivery Using Focused Ultrasound

Larabi M., Mackanos M., Shinde R., Contag C., Guccione S., Stanford University, US

Local delivery of therapeutic drugs will increase drug concentration at the site of treatment for maximum efficacy, and reduce systemic drug exposure. The encouraging results obtain in first phase of the clinical study of doxorubicin [...]
