Particle Swarm Optimization for Positioning the Coil of Transcranial Magnetic Stimulation

Figure 2

Positioning of the coil and the head model. During the stimulation, the distance between the coil and scalp was 10 mm, and its plane was tangential to the surface (a). The coil can move around the surface with a constant separation of 10 mm to the scalp (b). The rotational axis passed through the intersection point of the 8-shape coil and was perpendicular to the coil’s surface (c). 0° of the rotational angle was defined when the long axis of the coil was parallel to X coordinate. The rotation angle φ was defined hereafter.
