An X-ray paradoxical pulse bi-planar synchronous real-time imaging device and imaging method are disclosed in this invention, wherein the device comprises the second C-arm and the first C-arm slidably set on the said second C- arm, wherein the first X-ray generator and the first image receiver are mounted on the said first C-arm, and the second X-ray generator and the second image receiver are mounted on the said second C-arm. An imaging control device controls the pulse cycle and width of the said first X-ray pulse and second X-ray pulse, so that the said first X-ray pulse and second X-ray pulse do not mutually interfere or have low degree of interference in one cycle. Therefore, the synchronous real-time X-ray imaging of the said first imaging device and second imaging device can be realized. Furthermore, the said imaging control device can display the X-ray images in real time and synchronously by processing the said X-ray images.
