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: 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: An image processing apparatus includes a hardware processor that: calculates a representative signal value in a region where no signal value variations attributable to dynamic states of an object are present, in each of a plurality of frame images acquired by consecutively applying radiation onto the object a plurality of times, and extracts high-frequency components of changes over time in the calculated representative signal values; and corrects signal value variations attributable to a fact that an irradiation amount varies each time the radiation is applied, by subtracting the extracted high-frequency components from the plurality of frame images, respectively, or dividing the plurality of frame images by the extracted high-frequency components, respectively.

Abstract: A radiographic imaging system includes a radiographic imager, an optical imager and an optical imaging condition setter. The radiographic imager detects radiation emitted from a radiation source and passed through a subject to take a radiograph. The optical imager takes an optical image of a region including a region to which the radiation is emitted from the radiation source. The optical imaging condition setter sets an optical imaging condition of the optical imager based on a radiographic imaging condition for the radiograph.

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 an imaging condition used in radiographing the subject.

Abstract: A positioning support apparatus includes a hardware processor. The hardware processor obtains a radiographic image of a subject taken through a radiography. Based on the obtained radiographic image, the hardware processor detects a relative positional relationship between the subject and at least one of a radiation detector and a radiation source, the positional relationship being at a time when the radiographic image is taken. The hardware processor receives a change input for simulating a change of a position of the at least one of the radiation detector and the radiation source. Based on the detected positional relationship and the received change input, the hardware processor generates a simulation-reflected image that is an image of the subject reflecting the change of the position of the at least one of the radiation detector and the radiation source. The hardware processor outputs the generated simulation-reflected 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 irradiates the radiographic image capturing devices loaded in the holder at once. An image processor generates a plurality of images based on image data acquired by the radiographic image capturing devices. The image processor removes a streaky component residing in the generated image to correct the image. Such process includes forming a smoothed image by smoothing with a low-pass filter, and subtracting an interpolation image to extract a streaky image from the smoothing image and adding the streaky image to remove the streaky component. The smoothing includes reflecting smoothing on pixels showing a subject structure using a low-pass filter with a size larger in the horizontal direction compared to pixels other than pixels showing the subject structure.
