Title (EN) FITTING OF BRIGHTNESS IN A VISUAL PROSTHESIS
(FR) REGLAGE DE LUMINOSITE DANS UNE PROTHESE VISUELLE
Abstract: front page image
(EN)The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual patient. The perceptual response to electrical neural stimulation varies from patient to patient and The response to electrical neural stimulation varies from patient to patient and the relationship between current and perceived brightness is often non-linear. It is necessary to determine this relationship to fit the prosthesis settings for each patient. It is advantageous to map the perceptual responses to stimuli. The method of mapping of the present invention is to provide a plurality of stimuli that vary in current, voltage, pulse duration, frequency, or some other dimension; measuring and recording the response to those stimuli; deriving a formula or equation describing the map from the individual points; storing the formula; and using that formula to map future stimulation.
(FR)La présente invention concerne un procédé permettant de régler automatiquement une matrice d'électrode aux caractéristiques neurales d'un patient considéré. La réponse perceptive à la stimulation neurale électrique varie d'un patient à l'autre, la relation entre luminosité courante et luminosité perçus étant souvent non linéaire. Il est nécessaire de déterminer cette relation pour régler la prothèse en fonction de chaque patient. Il est avantageux d'appliquer à des stimuli les réponses perceptives. Le procédé d'application de la présente invention consiste à fournir une pluralité de stimuli dont on fait varier l'intensité, la tension, la durée d'impulsion, la fréquence, et quelques autres grandeurs. On mesure et on enregistre alors la réponse à ces stimuli. On dérive ensuite une formule ou équation décrivant l'application à partir de chacun des points. On conserve cette formule que l'on utilisera pour appliquer les stimulations futures.
