y étant la tension, t le temps, Ti la durée de la première partie ascendante, Θ une durée fonction de l'angle initial de la première partie ascendante et une durée fonction de l'angle initial de la seconde partie descendante.y being the voltage, t time, Ti the duration of the first ascending part, Θ a duration as a function of the initial angle of the first ascending part and a duration as a function of the initial angle of the second descending part.
Les moyens de réglage de ia forme des impulsions sont adaptés pour modifier ladite valeur Θ. Ainsi, si l'on choisit une durée égale à ~P| = 5 Θ pour la courbe ascendante, la forme de cette courbe sera égaie à :The means for adjusting the shape of the pulses are adapted to modify said value Θ. So, if we choose a duration equal to ~ P | = 5 Θ for the ascending curve, the shape of this curve will be equal to:
5 t Y = 1 - e ~5 t Y = 1 - e ~
De même si l'on choisit une durée égale à T2 ≈ 5 Θ pour la courbe descendante, la forme de cette courbe sera égale à :Similarly if we choose a duration equal to T 2 ≈ 5 Θ for the downward curve, the shape of this curve will be equal to:
(t - Tt) υ = p — 5(t - Tt) υ = p - 5
T2 T 2
Ces choix seront effectués par le praticien en fonction du traitement à prescrire et des cellules ou tissus à atteindre (tels que artères, veines, canaux lymphatiques, vessie, intestin, foie, rate, vésicule, pancréas). These choices will be made by the practitioner according to the treatment to be prescribed and the cells or tissues to be reached (such as arteries, veins, lymphatic channels, bladder, intestine, liver, spleen, vesicle, pancreas).
