Title
(EN) THERAPY PROGRAM SELECTION FOR ELECTRICAL STIMULATION THERAPY BASED ON A VOLUME OF TISSUE ACTIVATION
(FR) SÉLECTION DE PROGRAMME DE THÉRAPIE POUR UNE THÉRAPIE PAR STIMULATION ÉLECTRIQUE BASÉE SUR UN VOLUME D'ACTIVATION DE TISSU
Abstract
(EN)
In some examples, a processor of a system evaluates a therapy program based on a score determined based on a volume of tissue expected to be activated ("VTA") by therapy delivery according to the therapy program. The score may be determined using a three-dimensional (3D) grid comprising a plurality of voxels that are each assigned a value. The processor may register the VTA with the 3D grid and determine the score for the therapy program based on the values assigned to voxels with which the VTA overlaps. One or more therapy programs for electrical stimulation therapy (e.g., deep brain stimulation) may be selected based on the scores determined based on the 3D grid.
(FR)
Selon certains exemples de l'invention, un processeur d'un système évalue un programme de thérapie en se fondant sur un score déterminé sur la base d'un volume de tissu susceptible d'être activé ("VTA") par l'administration d'une thérapie selon le programme de thérapie. Le score peut être déterminé à l'aide d'une grille tridimensionnelle (3D) comprenant une pluralité de voxels à chacun desquels une valeur a été attribuée. Le processeur peut enregistrer la VTA avec la grille 3D et déterminer le score pour le programme de thérapie sur la base des valeurs attribuées aux voxels se chevauchant avec le VTA. Un ou plusieurs programmes de thérapie pour une thérapie de stimulation électrique (par exemple, une stimulation cérébrale profonde) peuvent être sélectionnés sur la base des scores déterminés sur la base de la grille 3D.
