Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A novel MR-guided brain therapy device operating at 1 MHz has been designed and constructed. The system has been installed and tested in a clinical 1.5 T Philips Achieva MRI. Skull bone distortions induced on the ultrasonic beam are corrected using the con ...
The ultrasound pulse transmission or echo technique is described for measuring the sp. interfacial area, bubble size, gas hold up, and no. of bubbles per unit vol. in gas-liq. dispersion. Expts. on the application of the method to simulated and real fermns ...
We present a new wavelet-based strategy for autonomous feature extraction and segmentation of cardiac structures in dynamic ultrasound images. Image sequences subjected to a multidimensional (2D plus time) wavelet transform yield a large number of individu ...
A method for extracting in real-time the position and size of liver vessels from 2D ultrasound images is described. It proceeds in two steps. Starting with a rough localization of the vessels using the scale-space theory, seed points are defined. Then, ves ...
An ultrasound pulse transmission technique was studied as an alternative means of measuring the specific interfacial area (a) in gas-liq. reactors. Characterization of gas-liq. dispersions using ultrasound can be a very valuable alternative in situations i ...
In this paper we show how healthy subjects can operate a non-invasive asynchronous BCI for controlling a FES neuroprosthesis and manipulate objects to carry out daily tasks in ecological conditions. Both, experienced and novel subjects proved to be able to ...

A method is presented for detg. the size distribution of spheres dispersed in a continuous phase by anal. of pulsed ultrasound signals reflected from members of the dispersion. Its theor. basis is developed for spherical bubbles and extended to nonspherica ...
