The IMRT Head and Torso Freepoint Phantom was designed in collaboration with David D. Loshek PhD. With this phantom, choose any point dose location within a circular area with diameter of 11.2 cm by simply adjusting the two rotating cylinders. Lung and bone equivalent rods can be positioned at any location within the circular area for assessment of heterogeneity correction. Remove the center cylinder from the phantom body to simulate head and neck set-ups.
