PROBLEM TO BE SOLVED: To reduce an artifact caused by difference in X-ray photographing conditions when photographing the same part of a subject by a plurality of photographing sequences by rotating an X-ray tube device and an X-ray detection device around the subject. SOLUTION: An X-ray control device detects a photographing angle set by a control operation table by a rotary encoder and determines X-ray photographing condition to be controlled to a target image density in synchronization with the detection signal, and determines the determined X-ray photographing condition as the X-ray photographing condition at a next photographing angle. At least X-ray photographing condition is stored in a memory by association with the photographing angle, and the X-ray photographing condition stored in the memory at the time of photographing in the photographing sequence on and after the second time is read out by corresponding to the photographing angle.
