发明名称 RADIOGRAPHIC IMAGE CAPTURING SYSTEM
摘要 A radiographic image capturing system includes the following. A capturing stand includes a holder to hold radiographic image capturing devices. A radiation irradiator is able to irradiate the radiographic image capturing devices at once. An image processor generates images based on image data acquired by the radiographic image capturing devices. The image processor removes a structural component derived from the front radiographic image capturing device, on the basis of a calibration image and the generated image. The calibration image is preliminarily generated based on the image data acquired by the rear radiographic image capturing device with no subject disposed. The generated image is generated based on the image data acquired by the rear radiographic image capturing device during actual image capturing. The image processor removes a streaky component residing in the generated image.

主权项 1. A radiographic image capturing system comprising: a capturing stand which includes a holder which is able to hold a plurality of radiographic image capturing devices; a radiation irradiator which is able to irradiate the radiographic image capturing devices loaded in the holder at once with radiation; and an image processor which generates a plurality of images based on image data acquired by the radiographic image capturing devices, wherein, an edge of a front radiographic image capturing device overlaps in an anteroposterior direction with an edge of a rear radiographic image capturing device in the holder in view from the radiation irradiator, the front radiographic image capturing device being a radiographic image capturing device close to the radiation irradiator among the radiographic image capturing devices loaded in the holder, the rear radiographic image capturing device being a radiographic image capturing device remote from the radiation irradiator among the radiographic image capturing devices loaded in the holder, the image processor removes a structural component derived from the front radiographic image capturing device projected on a generated image, on the basis of a calibration image and the generated image, the calibration image being preliminarily generated based on the image data acquired by the rear radiographic image capturing device irradiated with radiation with no subject disposed in front of the radiographic image capturing devices loaded in the holder of the capturing stand, the generated image being generated based on the image data acquired by the rear radiographic image capturing device during actual image capturing of a subject, and the image processor removes a streaky component residing in the generated image on the basis of the generated image, to correct the image.
