Claim Text:
1. An X-ray detector, comprising: a panel including a plurality of photo-sensing pixels, the photo-sensing pixels to receive an X-ray and to perform photoelectric conversion on the received X-ray to output electrical signals; and a read-out integrated circuit connected to the panel, the read-out integrated circuit to monitor whether the photo-sensing pixels receive the X-ray or not in a standby mode and to generate a self-triggering signal based on the electrical signals from the photo-sensing pixels, the self-triggering signal indicating that the photo-sensing pixels receive the X-ray, wherein the standby mode includes a first time period and a second time period, and wherein: during the second time period, the read-out integrated circuit charges the electrical signals, and during the first time period, the read-out integrated circuit reads out the electrical signals and resets the photo-sensing pixels by discharging the charged electrical signals, and wherein the second time period is equal to or longer than an irradiation time of the X-ray.
