Title (EN) METHODS FOR MONITORING ABLATION PROGRESS WITH DOPPLER ULTRASOUND
(FR) PROCÉDÉS DE SURVEILLANCE DE LA PROGRESSION D'UNE ABLATION PAR ÉCHO-DOPPLER
Abstract:
(EN) Systems and methods for treating tissue are disclosed. The target tissue is ablated. A real-time image of the target tissue is generated during the ablation. The real-time blood perfusion level of the target tissue is determined from the real-time image and compared to an initial blood perfusion level of the target tissue. The comparison provides a metric for the progress of the ablation, and ablation is halted when the real-time blood perfusion drops below a threshold level relative to the initial blood perfusion level.
(FR) L'invention concerne des systèmes et des procédés pour traiter des tissus. Le tissu cible est enlevé par ablation. Une image en temps réel du tissu cible est générée pendant l'ablation. Le niveau de perfusion sanguine en temps réel du tissu cible est déterminé à partir de l'image en temps réel et comparé à un niveau initial de perfusion sanguine du tissu cible. La comparaison fournit une mesure pour la progression de l'ablation, et l'ablation est arrêtée lorsque la perfusion sanguine en temps réel chute au-dessous d'un niveau seuil par rapport au niveau initial de perfusion sanguine.
