PURPOSE:To prevent any photographic error of two sides of a subject section for its two sides by transmitting X-ray fluoroscopic condition data concerning one of the sides to an X-ray controller installed on the other side. CONSTITUTION:A subject section 1 is examined by fluoroscopy from the FL side by means of devices 12-14 and 5. Optimum fluoroscopic tube voltage and current (FKV) and (FmA) are produced by an automatic luminance controller according to the state of the subject section 1. The X-ray controller 14 has a mechanism for automatically obtaining optimum photographic condition for the section 1 according to FKV and FmA. Therefore, photographic condition is automatically set in the X-ray controller 14 when fluoroscopic condition is determined. Following that, the fluoroscopic condition of the FL side is transmitted to the LA side of the subject section 1 through X-ray controllers 14 and 4 by means of a transmitter, thereby automatically setting photographic condition for the LA direction. Accordingly, it is possible to prevent any photographic error for the FL and the LA sides of the subject section 1. |
