Vidéos Q&A

Écoutez les fondateurs d’eMyosound parler de cette nouvelle approche révolutionnaire du diagnostic cardiaque.

Pourquoi l’évaluation de la rigidité myocardique est-elle un facteur critique dans la détection et la gestion des pathologies cardiaques, et comment eMyosound répond-il à ce besoin non satisfait ?

Qu’est-ce que le système eMyosound, et en quoi sa technologie d’ultrasons est-elle unique et innovante pour évaluer la rigidité cardiaque ?

Comparé aux méthodes d’imagerie conventionnelles, quels sont les avantages techniques de l’utilisation des ondes de cisaillement pour mesurer la rigidité du myocarde ?

Quel est le rôle de la sonde eMyosound dans la génération et le suivi des ondes de cisaillement, et comment cela contribue-t-il à la mesure quantitative de la rigidité des tissus ?

Quel rôle les instituts de recherche et les partenariats ont-ils joué dans la création et le développement d’eMyosound ?

Comment la vitesse de propagation des ondes de cisaillement est-elle directement liée à la rigidité des tissus ? Et comment le système eMyosound exploite-t-il cette relation pour fournir une évaluation quantitative ?

Quels ont été les jalons clés, comme la validation préclinique et la première preuve de concept chez l’homme, qui ont marqué le développement de la technologie eMyosound ?

Comment vous êtes-vous rencontrés et qu’est-ce qui vous a réunis ?

Comment décririez-vous la dynamique de votre équipe fondatrice ? Qui apporte quoi en termes de compétences et de personnalité ?

D’où est venue l’idée spécifique de développer une solution non invasive basée sur les ultrasons pour évaluer la rigidité cardiaque ? Quel vide cherchiez-vous à combler dans le domaine de la cardiologie ?

Quelle est la vision d’eMyosound pour l’avenir de la cardiologie, et comment prévoyez-vous de continuer à faire progresser ce domaine ?
