(a) A water equivalent MapPHAN phantom. (b) Image of phantom with 12 MeV electron beam. The vertical yellow lines indicate the line of the cone used to prevent electron beams from spreading outward. The black circle represents ion-chamber position for measuring the absolute dose. When the brightest point on the image is set to 100, the distance to the point at which the brightness is 20% is selected to estimate a practical range. The color is arbitrary, and it is shown in rainbow-like color.
