Claim Text:
1. A radiographic device which is connected to a radiation generation device irradiating a subject with radiation in order to allow communication therebetween and receives the radiation transferred through the subject so as to radiograph a radiological image of the subject, comprising: an image detection unit that has an imaging region where a plurality of pixels accumulating signal charges corresponding to a dose of the radiation are arranged and detects the radiological image; a dose detection unit that detects an arrival dose of the radiation arriving at the imaging region; a stop timing prediction unit that predicts a stop timing for stopping irradiation of the radiation in the radiation generation device based on the arrival dose detected by the dose detection unit and a preset dose target value in order to prevent excess radiation exposure to the subject; and a communication unit that sends a stop timing notification for notifying the stop timing to the radiation generation device before the stop timing arrives, wherein the communication unit sends the stop timing notification a predetermined time before the stop timing, the predetermined time being set in consideration of a time lag of communication with the radiation generation device, and wherein a time lag of the communication is an average time lag derived from multiple measurement points according to a communication path with the radiation generation device.
