Title: Apparatus and method for visualizing ultrasonic images
Inventor: DEKEL DORON
IPC: A61B8/08
Filed: 1997-11-28
Abstract: The present invention provides a system and method for visualizing internal images of an anatomical body. Internal images of the body are acquired by an ultrasound imaging transducer. The position and orientation of the ultrasound imaging transducer is tracked in a frame of reference by a spatial determinator. The position of the images in the frame of reference is determined by calibrating the ultrasound imaging transducer to produce a vector position of the images with respect to a fixed point on the transducer. This vector position can then be added to the position and orientation of the fixed point of the transducer in the frame of reference determined by the spatial determinator.  The position and orientation of a medical instrument used on the patient are also tracked in the frame of reference by spatial determinators.  The position and orientation of the instrument is mapped onto the position and orientation of the images. This information is used to generate processed images from the images acquired by the transducer. The processed images are generated from a view spatially related to the position of the instrument. The system is expandable so that more than one instrument and more than one transducer can be used.

Title: Hybrid tdm and atm voice switching central office and method of completing inter-office calls using same
Inventor: SYLVAIN DANY
IPC: H04L12/64
Filed: 1999-11-16
Abstract: A hybrid central office for serving a plurality of subscriber lines while serving as a virtual access tandem to a subnetwork of central offices having a connection to an ATM backbone network is described. The hybrid central office includes a computing module having a messaging interface to the ATM network, an inter--working trunk interface to the ATM network and a trunk connection to the PSTN. The hybrid central office serves as a tandem switch for other central offices connected to the subnetwork. Other central offices are preferably connected to the subnetwork by a signal large trunk group. A11 inter-office call routing is therefore handled by the hybrid central office. The hybrid central office also provides a gateway to the PSTN. Inter-office calls originated and terminated within the subnetwork are set up by the virtual access tandem but after call set up, the virtual access tandem is not involved in the call. The advantage is the utilization of spare processing capacity in a central office to off-load inter-office trunking congestion, as well as a significant reduction in trunking maintenance costs.

Abstract: On obtient une carte tridimensionnelle représentant la probabilité d'états fonctionnels cérébraux à partir des signaux électriques et/ou magnétiques (EEG/MEG) mesurés dans la surface du cuir chevelu. Pour ce faire, on obtient les paramètres descriptifs statistiques par EEG/MEG et on calcule une carte de la distribution cérébrale de ces derniers. La carte représente le résultat inverse par rapport à l'EEG/MEG et se fonde a) sur la restriction du résultat à des structures présentant une forte probabilité de générer une activité électrique, en utilisant un Atlas cérébral et b) sur le fait que le résultat présente une incertitude prédéterminée. On détermine la probabilité pour cette carte, ou pour un sous-ensemble de celle-ci, de faire partie d'un groupe modèle. Pour effectuer cette détermination, on modélise les corrélations spatiales de la carte, ainsi que sa dépendance aux covariables expérimentales. Les probabilités obtenues sont codifiées en une échelle de pseudo-couleurs et sont superposées sur un Atlas cérébral pour être interactivement visualisées en tridimension. Les Atlas cérébraux utilisés pour la résolution du problème inverse et pour la visualisation peuvent être des neuroimages individuelles, des Atlas de probabilités et des déformations plastiques d'un Atlas de probabilités par rapport à la morphologie d'un individu. On appelle cette méthodologie analyse quantitative électro/magnétoencéphalographique tomographique (qEEG-T).
