Photograph showing our IVR-CT system in the Hybrid ER (Aquilion PRIME, TSX-303B; Toshiba Medical Systems Corp., Tochigi, Japan). All life-saving procedures including airway management, emergency surgery, and transarterial embolization can be performed on the table without relocating the patient. a Sliding CT scanner with the two rows of rails on the floor, b CT examination and intervention table, c moveable C-arm, d 56-inch monitor screen, e ultrasonography equipment, and f mechanical ventilator. Unlike the usual CT scanner, after the patient is positioned on the CT examination and intervention table, the CT scanner moves to the table on rails with the table fixed. We use the room next to the Hybrid ER for surgical instrument storage and bring only what we need for the surgery into the Hybrid ER. The ventilator is located on the foot side of the trauma table. The blood refrigerator is located in the intensive care unit near the Hybrid ER. When an anaesthesiologist performs inhalation anaesthesia, the anaesthesia machine is located near the head side of the trauma table. Because the sliding CT scanner is moved to the adjacent CT suite after the CT scan, adequate space is available near the head side of the trauma table
