The temperature rise in the human brain due to the use of a mobile phone. (a) The vessel structure projected on the head, veins are shown in blue, arteries in red. (b) The temperature rise on a false-colour scale, with blue=0.0 and red=0.15 °C. The slice is taken in a left-right plane through the head at the level of the mobile-phone antenna. The outer contour of the head can be seen on the right-hand side. Note that the red zone is only present in the skull and skin tissue. Results taken from Van Leeuwen et al. 1999, with permission.3
