Abstract: In an X-ray imaging system a holding device holds an X-ray imaging unit that performs X-ray imaging of a subject, a bed supports a subject, and a driving unit moves the holding device and the bed. A position detector detects positions of the holding device and the bed either when X-ray imaging is performed and/or when the driving unit has not performed driving for a predetermined time or more. A memory stores positions of the holding device and the bed detected by the position detector in a time series. An operation unit selects positions of the holding device and the bed stored in time series in either a time-series sequence or a reverse time-series sequence. Based on instructions from the operation unit, the controller reads out detection results from the memory and drives the driving unit based on the detection results.
