Fig. 8.11 Manually generated head contour of a head phantom with overlying 3D laser scan
(dots). The laser scan provides more detailed information of the head's shape, in particular in the
facial area, compared to the manually generated head contour

again for stimulation. Figure 8.12 exemplarily shows the motor cortex mapping
results for two subjects.
During these TMS-experiments, we have found that the overall error of the
robotized system using laser scans is less than 5 mm. This has been measured as
