○ Radioprotective equipment was being used appropriately. ● Radioprotective equipment was used, but the method of use was inappropriate. Simultaneous irradiation = reduction of simultaneous frontal and lateral irradiation in fluoroscopy mode; Pulse rate reduction = appropriate selection/switching of fluoroscopy mode (changed from 15 to 7.5 pps); Irradiation field = restriction of irradiation field to target region; IR = dose reduction using iterative reconstruction (IR) during CT fluoroscopy; Shielding screens = ceiling‐mounted radiation‐shielding screens; C_u = under‐bed protective curtains; C_s = scatter‐radiation protection curtains; R = RADPAD^®; Evacuation from the room = room evacuation during imaging mode.
