Title
(EN) DELIVERING TUMOR TREATING FIELDS (TTFIELDS) TO THE NECK
(FR) ADMINISTRATION DE CHAMPS DE TRAITEMENT DE TUMEUR (CTT) AU COU
Abstract
(EN)
Tumor Treating Fields (TTFields) can be used to treat tumors (and/or prevent metastases) in or near a person's neck by affixing a first transducer array (i.e., a set of electrode elements) to the person's head and affixing a second transducer array to the person's chest. Subsequently, an AC voltage at a desired frequency (e.g., 100-300 kHz) is applied between the first transducer array and the second transducer array. This induces an electric field that is strong enough to be effective (e.g., greater than 1 V/cm) in most of the person's neck. In some embodiments, the center of the first transducer array is positioned on the vertex of the head or on an upper surface of the person's head. In some embodiments, the second set of electrode elements is positioned immediately below the base of the neck.
(FR)
Les champs de traitement de tumeur (CTT) peuvent être utilisés pour traiter des tumeurs (et/ou pour prévenir des métastases) dans ou à proximité du cou d'une personne par la fixation d'un premier réseau de transducteurs (c'est-à-dire un ensemble d'éléments d'électrode) au niveau de la tête d'une personne et par la fixation d'un deuxième réseau de transducteurs au niveau de la poitrine de la personne. Ensuite, une tension alternative d'une fréquence souhaitée (par exemple 100-300 kHz) est appliquée entre le premier réseau de transducteurs et le deuxième réseau de transducteurs. Ceci induit un champ électrique qui est suffisamment puissant pour être efficace (par exemple, supérieur à 1 V/cm) dans la majeure partie du cou de la personne. Dans certains modes de réalisation, le centre du premier réseau de transducteurs est positionné sur le sommet de la tête ou sur une surface supérieure de la tête de la personne. Dans certains modes de réalisation, le deuxième ensemble d'éléments d'électrode est positionné immédiatement au-dessous de la base du cou.
