Abstract: A radiographic imaging support system that supports positioning of a radiographing site of a subject with respect to a radiographic imaging apparatus, includes a hardware processor that acquires image information based on an optical image obtained by capturing an image of the radiographing site with an optical camera, generates first target position information regarding a target position of the radiographing site, and outputs the generated first target position information. The first target position information includes information corresponding to a size of the radiographing site.

Abstract: A dynamic image analysis apparatus includes a hardware processor; and an ouputter. The hardware processor obtains a dynamic image of a chest portion obtained by dynamic imaging by radiation. The hardware processor performs a first generating process in which information regarding pleural adhesion is generated based on a motion amount in a region including at least a region adjacent to a rib cage in a lung region in the dynamic image. The outputter outputs the generated information regarding the pleural adhesion.

Abstract: A radiographing control apparatus includes a hardware processor. A radiographic imaging apparatus is exposed to a radiation from an irradiating apparatus through the subject. The hardware processor retrieves pre-exposure image data which the radiographic imaging apparatus generates by performing a pre-exposure to the subject at a pre-exposure dose of less than a dose of a subsequent main exposure, and calculates a total dose required to obtain diagnostic image data to be used for diagnosis. The hardware processor outputs a main exposure dose based on the calculated total dose to the irradiating apparatus and the radiographic imaging apparatus. The hardware processor retrieves main exposure image data which the radiographic imaging apparatus generates by performing the main exposure to the subject at the main exposure dose, and combines the main exposure image data with the pre-exposure image data to generate the diagnostic image data.

Abstract: An image processing apparatus includes a hardware processor. The hardware processor estimates a body thickness and an irradiation field region of a subject based on a radiograph obtained by radiographing the subject. Further, the hardware processor calculates a distance from a focus of a radiation source to a radiation entrance point based on the body thickness. Still further, the hardware processor calculates an irradiation field size based on the irradiation field region. Yet further, the hardware processor calculates an exposure dose based on the distance, the irradiation field size, and in imaging condition used in radiographing the subject.

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.
