Examples of a CT scan of a (tipical) SEEG implant, characterized by a high number of electrodes (targetting deep brain structures from the cortical surfaces). (a) Gray-scale surface models representing an example of image resulting from a CT scan opportunely thresholded to separate between contact and brain tissue. (b) SEEG implants aim to characterize the EZ thus it is quite common that several electrodes have narrow trajectories pointing at the same region from different sides. The artifact around each contact that blurs the exact geometry of the cylinder results in electrodes that apparently touch each other or (c) even apparently seem to be sequential traversing the whole brain.
