Abstract

Selon des modes de réalisation, la présente invention concerne un ensemble de capteurs et/ou des systèmes de mesures par ultrasons/optiques qui peuvent fournir des informations concernant des paramètres hémodynamiques. Un faisceau d’ultrasons peut être utilisé pour générer un champ doppler pour des éléments optiques d’un ensemble de capteurs. En combinant les informations reçues des éléments ultrasonores et optiques de l’ensemble de capteurs, des valeurs plus précises pour les paramètres hémodynamiques peuvent être déterminées.
