Abstract

POUR MESURER LE DEBIT D'UN FLUIDE DANS UN CONDUIT 20, ON EMET DANS CE FLUIDE UN CHAMP ULTRASONORE UNIFORME, ON DETERMINE UN SIGNAL DOPPLER A PARTIR DU SIGNAL RECU EN FAISANT EN SORTE QUE LA REGION D'ECHANTILLONNAGE SOIT NORMALE A LA DIRECTION DE PROPAGATION DU CHAMP SONORE, ET ON CALCULE L'INTEGRALE DE LA PUISSANCE SUR CETTE REGION. ON DETERMINE ENSUITE UN FACTEUR D'ETALONNAGE POUR LA VALEUR OBTENUE, EN EFFECTUANT UNE MESURE DE PUISSANCE QUI PORTE SUR UN VOLUME DE FLUIDE CONNU SITUE ENTIEREMENT A L'INTERIEUR DU CONDUIT. L'INVENTION S'APPLIQUE PARTICULIEREMENT A LA MESURE DU DEBIT SANGUIN DANS LE SYSTEME CIRCULATOIRE D'UN PATIENT.
