Title
(EN) SYSTEM FOR GENERATING SYNTHETIC APERTURE ULTRASOUND IMAGES DURING NEEDLE PLACEMENT
(FR) SYSTÈME DE PRODUCTION D'IMAGES D'OUVERTURE SYNTHÉTIQUES PAR ULTRASONS PENDANT LA MISE EN PLACE D'UNE AIGUILLE
Abstract
(EN)
An aspect of the present disclosure is to provide a device or needle placement system including a needle having a proximal end and a distal end, and an ultrasound transducer element attached to the distal end of the needle. The system also includes a needle constraining assembly configured to receive and constrain the needle to only rotational degrees of freedom within a range of angular motion. The system further includes a needle sensor system incorporated into the constraining assembly to sense an angular orientation of the needle with the range of angular motion. The system also includes an ultrasound data processor configured to communicate with the transducer element to receive ultrasound detection signals and communicate with the needle sensor system to receive needle angular orientation signals. Based on the ultrasound detection and the needle angular orientation signals, the ultrasound data processor can calculate synthetic aperture ultrasound images.

La présente invention concerne un dispositif ou un système de mise en place d'aiguille comprenant une aiguille présentant une extrémité proximale et une extrémité distale, et un élément transducteur ultrasonore fixé à l'extrémité distale de l'aiguille. Le système comprend également un ensemble de contrainte d'aiguille conçu pour recevoir et contraindre l'aiguille uniquement à des degrés de liberté de rotation dans une plage de mouvements angulaires. Le système comprend en outre un système détecteur d'aiguille incorporé dans l'ensemble de contrainte en vue de détecter une orientation angulaire de l'aiguille à l'intérieur de la plage de mouvements angulaires. Le système comprend également un processeur de données ultrasonores conçu pour communiquer avec l'élément transducteur en vue de recevoir les signaux de détection ultrasonores et communiquer avec le système détecteur d'aiguille en vue de recevoir des signaux d'orientation angulaire d'aiguille. Sur la base de la détection ultrasonore et des signaux d'orientation angulaire d'aiguille, le processeur de données ultrasonores peut calculer les images d'ouverture synthétiques par ultrasons.
