In the present invention, disclosed are an alignment bite of an X-ray imaging device to align a photographic subject at an X-ray imaging position, and an X-ray imaging device having the alignment bite. The alignment bite according to an embodiment of the present invention comprises: a support unit which is connected to a bite installation base supporting the alignment bite to rotate; and a bite unit which is connected to the support unit to rotate. The support unit includes a link frame which connects the bite installation base to the bite unit to support the bite unit, a first joint which connects one side of the link frame to the bite installation base to rotate, a second joint which connects the other side of the bite unit to the other side of the link frame to rotate, and a third joint which is provided between the first joint and the second joint such that the link frame is foldable. According to the present invention, an interested area requiring image information can be accurately aligned in an imaging focus area by the joint-structure alignment bite. Therefore, it is possible to acquire accurate image information. It is possible to reduce an operation range of an X-ray generator and a detector. It is possible to simplify a driving mechanism. There is no restriction in an imaging-available area by changing an alignment direction of a photographic subject, and thus a position of an imaging-available interested area can be significantly expanded. |
