Abstract

Irradiation with a single beam of focused ultrasound is currently the method of choice for the production of trackless, focal, pan-necrotic lesions of predetermined size at any desired site within the central nervous system of experimental animals and man. Development of a simple technique using the same transducer for concurrent detection of the production of such lesions is described and the results obtained in a phantom brain are presented.

Sommaire

L'irradiation par un faisceau isolé d'ultrasons focalisés est de façon courante la méthode de choix pour la production de lésions sans traces, focales et nécrotiques, de taille prédeterminée à n'importe quel endroit à l'intérieur du système nerveux central d'animaux d'expérimentation et de l'homme. On décrit la mise au point d'une technique simple, utilisant le même dispositif pour la détermination simultanée de la production de telles lésions et on rend compte des résultats obtenus sur un cerveau fictif.

Zusammenfassung

Die Bestrahlung mit einem Einzelstrahl von fokussiertem Ultraschall ist gegenwärtig die Methode der Wahl zur Erzeugung von spurenfreien, fokalen, pan-nekrotischen Läsionen vorbestimmter Große in jedem gewünschten Gebiet des Zentralnervensystems von Versuchstier und Mensch. Die Entwicklung eines Verfahrens wird beschrieben, das denselben Transducer zur gleichzeitigen Verfolgung der Setzung solcher Läsionen verwendet. Die an einem Phantomgehirn gewonnenen Ergebnisse werden mitgeteilt.
