Abstract

The paper describes a method for processing input/output blood velocity waveforms for femoral arteries obtained from ultrasonic Doppler flowmeters. Normal, diseased and early cases of disease are discussed, and it is shown that a pictorial display of the roots of a quadratic equation provide a simple quantitative assessment of progress and treatment of disease

Sommaire

La thèse décrit une méthode de traitement des ondes de vitssse d'arrivée/sortie du sang dans les artères fémorales, grâce à des débitmètres Doppler à ultrasons. Elle commente quelques cas normaux et débuts de maladies, et l'on constate qu'un affichage illustré des racines d'équation du second degré fournit une évaluation quantitative simple du progrès et du traitement de la maladie.

Zusammenfassung

Die Arbeit beschreibt ein Verfahren zur Verarbeitung durch Ultraschall-Doppler-Durchflußmesser gewonnener Eingangs/Ausgangs-Durchblutungsgeschwindigkeitswellenformen für Schenkelarterien. Es werden normale und erkrankte sowie Fälle im Anfangsstadium der Erkrankung untersucht, und es wird gezeigt, daß eine bildliche Darstellung der Wurzeln einer Quadratgleichung eine einfache quantitative Bewertung des Fortschreitens und der Behandlung von Erkrankungen ermöglicht.
