What the experts said
Stereotactic frames convert the head into a stable 3D coordinate system to place DBS electrodes within 1 mm of the target.
The concept of stereotaxis began with Horsley & Clarke and was later adapted for human use.
Arc-radius frames work on the principle that the target sits at the centre of the arc.
Frame-based systems remain the reference standard in DBS despite the availability of robotic and frameless systems.
