Abstract

PROCEDE ET APPAREIL PERMETTANT LA CORRECTION D'ERREURS PAR COINCIDENCE AFFECTANT LA DETECTION ET LE COMPTAGE AUTOMATISES DE PARTICULES MELANGEES AYANT DES CARACTERISTIQUES DETECTABLES DE NIVEAUX DIFFERENTS DANS DES APPLICATIONS DU COMPTAGE DE PARTICULES OU LA DETECTION DE PARTICULES "DOMINANTES", DANS DES CONDITIONS DE COINCIDENCE ENTRE PARTICULES, REND INDETECTABLES LES PARTICULES "DOMINEES", CE QUI SE TRADUIT PAR UNE INEXACTITUDE RESULTANTE DU COMPTE DES PARTICULES "DOMINEES". SUIVANT L'INVENTION, ON CORRIGE CETTE INEXACTITUDE EN MODIFIANT LE COMPTE P DES PARTICULES "DOMINEES" EN FONCTION DE LA DUREE TT DES SIGNAUX QUI SONT ENGENDRES EN REPONSE A LA DETECTION DES PARTICULES "DOMINEES". APPLICATION PARTICULIERE A LA NUMEROTATION GLOBULAIRE ET, NOTAMMENT, AU DENOMBREMENT PRECIS DES GLOBULES ROUGES ET DES PLAQUETTES D'ECHANTILLONS SANGUINS.
