Title (EN) APPARATUS AND METHOD FOR TRACKING A MEDICAL ULTRASONIC OBJECT
(FR) APPAREIL ET PROCÉDÉ POUR SUIVRE UN OBJET ULTRASONORE MÉDICAL
Abstract:
(EN) A vascular occlusion treatment system includes an ultrasound imaging system having an imaging control circuit communicatively coupled to an ultrasound imaging probe and to a display screen, and an ultrasonic vibration system having an ultrasonic generator operatively coupled to a medical ultrasonic object, such as an ultrasonic catheter. The ultrasonic catheter has a corewire with a distal tip. The ultrasonic generator has a generator control circuit that alternatingly switches between an ultrasonic work frequency and a tracking frequency. The generator control circuit sends a notification to the imaging control circuit when the generator control circuit has switched from the ultrasonic work frequency to the tracking frequency. The imaging control circuit responds by initiating a search in an ultrasound imaging space to locate the distal tip that is vibrating at the tracking frequency, and indicating a location of the distal tip in the ultrasound image displayed on the display screen.
(FR) L'invention concerne un système de traitement d'occlusion vasculaire qui comprend un système d'imagerie ultrasonore ayant un circuit de commande d'imagerie couplé de manière communicative à une sonde d'imagerie ultrasonore et à un écran d'affichage, et un système de vibration ultrasonore ayant un générateur d'ultrasons couplé de manière fonctionnelle à un objet ultrasonore médical, tel qu'un cathéter à ultrasons. Le cathéter à ultrasons comprend un fil de noyau doté d'une pointe distale. Le générateur d'ultrasons comprend un circuit de commande de générateur qui commute de manière alternée entre une fréquence de travail ultrasonore et une fréquence de suivi. Le circuit de commande de générateur envoie une notification au circuit de commande d'imagerie lorsque le circuit de commande de générateur a commuté de la fréquence de travail ultrasonore vers la fréquence de suivi. Le circuit de commande d'imagerie répond en initiant une recherche dans un espace d'imagerie ultrasonore, pour localiser la pointe distale qui vibre à la fréquence de suivi, et en indiquant un emplacement de la pointe distale dans l'image ultrasonore affichée sur l'écran d'affichage.
