Abstract: In an X-ray dose management system, a dental radiograph device includes an imaging condition setter, an output information creator, and an information communicator that sends the output information to a wireless tag. An X-ray imaging element includes an X-ray image information obtainer and a wireless tag. An information reading device includes an output information reader and an information communicator that sends the read output information to an information terminal. The information terminal includes a patient information retriever that retrieves patient information from a patient information storage, a communicator that receives the output information, and an output information processor that records the output information and the patient information in association with each other in the patient information storage.

Abstract: A panoramic imaging apparatus is provided, which is able to freely display a focus-optimized internal structural image of the tooth row depending on a position using image data acquired by only one-time X-ray panoramic imaging from an arbitrary section along a patient's tooth row. The panoramic imaging apparatus comprise an X-ray source (31) and a detector (32) outputting a digital electrical signal depending on an incident X-ray at a constant frame rate.
