Therefore, the amount of exposure can be reduced as compared with the conventional one. Particularly, in recent years, the performance of the imaging device has been improved and the imaging time has been shortened. However, if such an imaging device is used, the effect of reducing the amount of exposure can be obtained more remarkably.
- the fluoroscopic imaging device 300 may communicate with the controller device 150 so that the distance between the times t1, t2 and / or L1-L2 is automatically input from the fluoroscopic imaging device side to the controller device.
- the present invention is not limited to the configuration in which the distance between L1 and L2 is input, and a configuration in which the distance between L1 and L2 is automatically calculated when the position of L1 and the position of L2 are input may be employed.
- controller device 150 may be connected to a network, and data such as a chemical solution injection condition and a scan condition may be given to the controller device 150 via the network.
