Abstract

L'invention concerne un procédé permettant de déterminer un changement de rétention d'eau dans une partie du corps, à savoir dans le pied et/ou dans la jambe (1). Des représentations tridimensionnelles de la partie du corps sont élaborées au moyen d'au moins une unité de prise de vues (3) et sont évaluées. Selon l'invention, au moins une grandeur de départ située à la surface de la partie du corps, à savoir un point de mesure (27, 29) et/ou une ligne ou une courbe de mesure (33, 34, 35) est sélectionnée et est établie sur la base des représentations de la partie du corps. Au moins un paramètre dépendant du volume de la partie du corps et par conséquent de la rétention d'eau, à savoir la position et/ou l'écart (A) entre la grandeur de départ et au moins une grandeur de référence sélectionnée parmi les représentations enregistrées ou une grandeur de référence établie dans ces représentations, à savoir un point de référence (37), une ligne ou une courbe de référence (38) et/ou un plan de référence (25), est déterminé. La détermination du paramètre est répétée une fois un certain laps de temps écoulé, en particulier au cours de la même procédure, et une variation de ce paramètre se traduit par une modification de la rétention d'eau dans la partie du corps.
