[0004] Now, the preparation for the patient replacement is completed, and the person carrying the patient using the stretcher (nurse etc.)
Calls for support for patient replacement (operation 104).
Usually, about six people are required to transfer the patient from the stretcher to the transport device, and the patient waits on the stretcher until the hands are gathered.

When the six persons are prepared, the patient is placed on the carrier together with the blanket by holding the end of the blanket prelaid under the patient laterally placed on the stretcher for each arrangement (operation 105). . After the replacement work is completed, in operation 106, the Z axis (the transport direction of the transport device, generally the body axis direction of the subject) is adjusted (the imaging range is confirmed), and the patient is fixed on the transport device. (Operation 107).

After the patient is secured on the carrier, the desired exam is performed (operation 108). After the inspection is completed, the stretcher is carried in again (operation 109), and the height of the top plate of the transfer device and the height of the table of the stretcher are adjusted (operation 110).
