Publication number: 20240179426Abstract: A radiation image apparatus without synchronous communication includes a pixel circuit, a reading circuit, a drive control circuit, an image processing circuit, a time measuring circuit, and a management circuit. The pixel circuit includes an imaging element configured to generate image data based on radiation and a detecting element configured to generate irradiation data of irradiation with the radiation. The reading circuit is configured to read the image data and the irradiation data. The drive control circuit is configured to control a first time when the image data is read by the reading circuit. The image processing circuit is configured to perform correction of the read image data. The time measuring circuit is configured to measure a second time related to the irradiation with the radiation based on the irradiation data. The management circuit is configured to manage the correction based on the first time and the second time.Type: ApplicationFiled: November 21, 2023Publication date: May 30, 2024Inventor: YOHEI KOIKE
