(c)With radiation protective curtain. A: Body phantom instead of patient (PBU-60, Kyoto Kagaku Co., Kyoto, Japan). B: Radiation protective curtain (39 × 43 cm, 0.25-mm Pb-equivalent thickness, 90 cm from the CT isocenter, with the upper edge of the curtain at a height of 185 cm from the ground). C: Body phantom instead of CT-assisting personnel (Alderson RANDO phantom). D: Isocenter of CT gantry. E: GD-352M affixed at the forehead of the phantom (100 cm from the CT isocenter, at a height of 160 cm from the ground).
