Title
(EN) APPARATUS, SYSTEMS, AND METHODS FOR OPTIMIZING DELIVERY OF RADIATION TO TREAT CARDIAC ARRHYTHMIAS
(FR) APPAREIL, SYSTÈMES ET PROCÉDÉS POUR OPTIMISER LA DISTRIBUTION DE RAYONNEMENT POUR TRAITER DES ARYTHMIES CARDIAQUES
Abstract
(EN)
Apparatus, systems, and methods are provided for optimizing radiation therapy to a patient to treat cardiac arrhythmias. The system generally includes an ultrasound device placed within the esophagus to image and map cardiac structures in real-time. The system may also control the ventilation of the patient to optimize ultrasound monitoring and radiation delivery. The device in the esophagus is designed to position and monitor the esophagus and/or nearby structures to optimize radiation delivery to targets while minimizing radiation to other key structures. In addition, different ablation technologies may be delivered from within the esophagus to ablate certain tissues that cannot be safely ablated with radiation therapy. Finally, the esophageal device may have electrical or magnetic properties that can be used to guide the radiation therapy.
(FR)
L'invention concerne un appareil, des systèmes et des procédés pour optimiser une radiothérapie à un patient pour traiter des arythmies cardiaques. Le système comprend généralement un dispositif à ultrasons placé à l'intérieur de l'oesophage pour imager et cartographier des structures cardiaques en temps réel. Le système peut également commander la ventilation du patient pour optimiser la surveillance ultrasonore et l'administration de rayonnement. Le dispositif dans l'oesophage est conçu pour positionner et surveiller l'oesophage et/ou les structures proches pour optimiser l'administration de rayonnement à des cibles tout en réduisant au minimum le rayonnement vers d'autres structures clé. De plus, différentes technologies d'ablation peuvent être administrées depuis l'intérieur de l'oesophage pour éliminer certains tissus qui ne peuvent pas être éliminés en toute sécurité avec une radiothérapie. Enfin, le dispositif oesophagien peut avoir des propriétés électriques ou magnétiques qui peuvent être utilisées pour guider la radiothérapie.
