RADIOGRAPHIC DEVICE

PROBLEM TO BE SOLVED: To flexibly switch a radiographing method in a radiographic device capable of imaging subtraction tomographic images.SOLUTION: In a radiographic device, whether to transmit an X-ray emitted from an X-ray tube 3 through a filter 25f for subtraction imaging can be switched by rotating a holder 25. Namely, when radiographing is to be performed with the X-ray being not transmitted through the filter 25f for subtraction imaging subsequently to radiographing with the X-ray being transmitted through the filter 25f for subtraction imaging, the radiographing can be immediately continued by rotating the holder. As a result, radiographing can be flexibly performed in the radiographic device.
