title: Head phantoms for neutron capture therapy.
abstract: A water-filled head phantom that is designed for use in boron neutron capture therapy is described. The shape of this ellipsoidal phantom, based on the Synder head model, and its composition are designed to simulate the neutron slowing down properties of the human skull and brain. Small ion chambers or activation foils can be placed in many locations within the phantom volume. This permits accurate three-dimensional mapping of all relevant dose components and use of these dose contours for beam development as well as for benchmarking of computer-based patient treatment codes.
