Abstract: A mammography apparatus includes a radiation source driver that moves a radiation source to a plurality of imaging positions including a first imaging position where LE imaging of emitting radiation R with low energy from the radiation source to capture a radiation image is performed, and a second imaging position where the LE imaging and HE imaging of emitting radiation R with high energy to capture a radiation image are performed, and a controller that causes a radiation detector to perform the LE imaging at the first imaging position in a state where the radiation source is moved, and causes the radiation detector to perform the LE imaging and the HE imaging at the second imaging position in a state where the movement of the radiation source is stopped or the radiation source is moved at a moving speed slower than that at the first imaging position.

Abstract: Targeting of a lesion which is performed by a stereoscopic biopsy device or the like is performed simply and highly accurately. Designation of a predetermined position in the stereoscopic image is received to acquire position information when a stereoscopic image is displayed, radiological images of radiographing directions are displayed as two-dimensional images, a mark based on the position information, which is designated in the stereoscopic image, is displayed in the two-dimensional images, designation of a predetermined position in the two-dimensional images is further received to acquire the position information after the mark is displayed.

Abstract: Disclosed are a radiation imaging system, an image processing device, a radiation imaging method, and a non-transitory computer-readable recording medium having an image processing program recorded thereon which facilitate the confirmation of a positional relationship between an object of interest and a biopsy needle. In the system using a radiation imaging device as a mammography device, when performing a biopsy of a breast of a subject, the positional relationship is confirmed using a radiation image (projection image) obtained through tomosynthesis imaging. A control unit reconstructs the projection image to generate a tomographic image in a state where the needle is inserted into the breast and generates a reprojection image at a predetermined angle from the tomographic image. The control unit extracts an image of the needle from the projection image, synthesizes the extracted image of the needle into the projection image while aligning, and displays the projection image.

Abstract: Disclosed are a radiation imaging system, an image processing device, and a non-transitory computer-readable recording medium having an image processing program recorded thereon which facilitate the confirmation of a positional relationship between an object of interest and a biopsy needle. A control unit of a console reconstructs a projection image obtained by tomosynthesis imaging to generate a tomographic image parallel (an x-y-axis direction) to an imaging surface in a state where a needle is inserted into a breast, and specifies an image of an object of interest from the tomographic image. The control unit generates a sectional image which includes the specified image of the object of interest and an image of the needle and intersects the imaging surface. The control unit generates an image of the needle from the projection image, synthesizes the generated image of the needle into the sectional image while aligning, and displays the sectional image.

Abstract: Provided are a radiography device, a radiography method, and a radiography program which can obtain an accurate radiographic image while reducing a burden on a subject. A radiography device control unit determines imaging conditions including at least one of resolution or an incident angle range, on the basis of a radiographic image captured before tomosynthesis imaging, and performs tomosynthesis imaging. Specifically, the radiography device control unit controls tomosynthesis imaging (120) such that tomosynthesis imaging is performed under first conditions (108) of low resolution and a narrow incident angle range in a case in which a mutation site suspected as a lesion is not detected and tomosynthesis imaging is performed under second conditions (112, 116, and 118) which are different from the first conditions in at least one of the resolution or the incident angle range in a case in which the mutation site suspected as a lesion is detected.

Abstract: A control device including: a control unit that, in a case in which continuous imaging that irradiates a breast of a subject with radiation emitted from a radiation source to capture a radiographic image in a compressed state in which the breast is compressed against an imaging table by a compression member and then captures an ultrasound image of the breast in the compressed state is performed, performs control to locate the radiation source at a non-facing position where the radiation source and the imaging table do not face each other.

Abstract: A radiography system includes a mammography apparatus and a control device including a compression control unit that, in a case of performing continuous imaging in which the simple imaging and the tomosynthesis imaging are continuously performed while the breast being compressed by the mammography apparatus, performs control to cause a compression member to compress the breast at a first force in a first imaging of the simple imaging or the tomosynthesis imaging that is performed first in the continuous imaging, to change a force of the compression member compressing the breast from the first force to a second force lower than the first force after the first imaging, and to cause the compression member to compress the breast at the second force in a second imaging that is performed later.
