Title
(EN) NEAR-INFRARED ANALYSIS OF TISSUE FAT PERCENTAGE
(FR) ANALYSE UTILISANT UN RAYONNEMENT PROCHE DES INFRAROUGES POUR DETERMINER LE POURCENTAGE DE GRAISSE DANS UN CORPS
Abstract
(EN)
Method and apparatus for determining percent fat in a body wherein near-infrared radiation (16, 16') is transmitted into the body to achieve optical interactance between the body and the near-infrared radiation. Optical absorption by the body at one or more wavelengths of the near-infrared radiation is measured (28, 29). The measured absorption of near-infrared radiation is utilized to quantitatively determine the fat content of the body. Data on a plurality of physical parameters of the body, such as height, weight, exercise level, sex, race, waste-to-hip measurement and arm circumference, can be utilized along with the measured near-infrared absorption in the quantitative determination of body fat content.
(FR)
Procédé et appareil permettant de déterminer le pourcentage de graisse dans un corps, consistant à transmettre un rayonnement proche des infrarouges (16, 16') dans le corps pour obtenir une interactance optique entre le corps et le rayonnement proche des infrarouges. L'absorption optique par le corps à une ou plusieurs longueurs d'ondes de rayonnement proche des infrarouges est mesurée (28, 29). L'absorption mesurée du rayonnement proche des infrarouges est utilisée pour déterminer de manière quantitative la teneur en graisse du corps. Des données concernant plusieurs paramètres physiques du corps tels que la hauteur, le poids, le niveau d'exercice, le sexe, la race, les mensurations taille/hanche et la circonférence des bras, peuvent être utilisées avec l'absorption mesurée du rayonnement proche des infrarouges pour la détermination quantitative de la teneur en graisse du corps.
