OPTIMAL DEEP BRAIN STIMULATION ELECTRODE SELECTION AND PLACEMENT ON THE BASIS OF STIMULATION FIELD MODELLING

摘要

Disclosed is a computer-implemented medical data processing method for planning a position of an electric stimulation device for neurostimulation of at least two target regions (TV1, . . . , TVN) disposed in an anatomical body part of a patient's body, the electric stimulation device (7) comprising at least two electric contacts, the method comprising executing, on at least one processor of at least one computer (3), steps of: a) acquiring (S1.1), at the at least one processor, medical image data describing a digital image of the anatomical body part, wherein the anatomical body part contains at least two target regions (TV1, . . . , TVN); b) determining (S1.2), by the at least one processor and based on the medical image data, target position data describing a position of each target region (TV1, . . . , TVN) in the anatomical body part; c) acquiring (S1.3), at the at least one processor, electric stimulation device geometry data describing a distance between the at least two contacts of the electric stimulation device (7); d) determining (S1.4), by the at least one processor and based on the target position data, target distance data describing a distance between each pair of the at least two target regions; e) determining (S1.5), by the at least one processor and based on the target position data and the target distance data and the electric stimulation device geometry data, electric stimulation device position data describing a stimulation position which is a relative position between the at least two target regions (TV1, . . . , TVN) and the electric stimulation device (7) which allows for stimulation of the at least two target regions (TV1, . . . , TVN) by the electric stimulation device (7).
