Abstract: A radiation image capturing system includes a radiation image capturing apparatus, an irradiation apparatus and an image processing apparatus. The image processing apparatus generates a first radiation image of a subject based on a signal value generated by the radiation image capturing apparatus with no grid attached irradiated by the irradiation apparatus; performs a low-pass filter process on a pixel value of the first radiation image using a scattering kernel, thereby generating a low frequency image; estimates a body thickness of the subject based on the signal value; estimates a scattered ray content rate based on the body thickness; calculates a scattered ray component in the first radiation image based on the low frequency image and the scattered ray content rate; and subtracts the scattered ray component from the first radiation image, thereby generating a second radiation image.

Abstract: 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.
