PROBLEM TO BE SOLVED: To provide an X-ray diagnostic device which suppresses uneven brightness generated in an image by suppressing influence of variation in bias voltage. ! SOLUTION: In an X-ray diagnostic device 1, an X-ray tube control part 6 and an FPD control circuit 29 allow X-ray irradiation and image reading-out to be performed on the basis of synchronization signals in an equal cycle. The image reading-out is performed after the elapse of a preset period from the X-ray irradiation with an equal interval for every two or more synchronization signals. If the image reading-out is performed immediately after the X-ray irradiation, a charge amount to be accumulated other than an electric charge generated in a conversion layer is changed between the image reading-out and image reading-out immediately before the X-ray irradiation in especially successive photographing at a low rate and one-shot photographing due to influence of variation in bias voltage Vh with the X-ray irradiation, and the changed char |
