Title
(EN) SYSTEM FOR ASSESSING TISSUE SUBSTANCE EXTRACTION
(FR) SYSTÈME POUR ÉVALUER L'EXTRACTION DE SUBSTANCE TISSULAIRE
Abstract
(EN)
The present invention relates to a system for measuring a micro-vascular flow distribution of a tissue portion of a mammal comprising means (101) for measuring a first indicator (MTT) for the blood flow through acapillary bed, means (102) for measuring a second indicator (CTTH) of heterogeneity of the blood flow in said capillary bed, and a first processor (110) arranged for using the first and the second indicator to estimate an extraction capacity (EC) of a substance from the blood in said capillary bed.
(FR)
La présente invention concerne un système pour mesurer une distribution de flux microvasculaire d'une partie de tissu d'un mammifère comprenant des moyens (101) pour mesurer un premier indicateur (MTT) pour le flux sanguin à travers un lit capillaire, des moyens (102) pour mesurer un deuxième indicateur (CTTH) d'hétérogénéité du flux sanguin dans ledit lit capillaire, et un premier processeur (110) agencé pour utiliser le premier et le deuxième indicateurs pour estimer une capacité d'extraction (EC) d'une substance à partir du sang dans ledit lit capillaire.
