Abstract: A mammography apparatus includes a compression control unit that, in a case in which continuous imaging that captures a radiographic image of the breast compressed by a compression plate and then captures an ultrasound image of the breast while maintaining the compressed state is performed, performs control to set a force of the compression plate compressing the breast to a first force in the capture of the radiographic image and to change the force of the compression plate compressing the breast from the first force to a second force lower than the first force in the capture of the ultrasound image.

Abstract: A control unit of a radiation imaging apparatus performs control of moving a radiation source, and emitting radiation from the radiation source at a plurality of positions at which incidence angles of the radiation to a breast of a subject are different from each other. The control unit performs control of causing a radiation detector to detect the radiation emitted from the radiation source at the plurality of positions. The control unit performs control of moving the radiation source at a movement speed corresponding to a position of the radiation source for a subject face proximate position.

Abstract: The radiation-irradiation device includes: a radiation generating unit that generates radiation; a collimator unit that controls an irradiation range to be irradiated with the radiation generated by the radiation generating unit; and an interval ensuring unit that includes a contact member being in contact with a subject to be irradiated with the radiation in a case in which a distance between the radiation generating unit and the subject is shorter than a preset distance, and ensures an interval between the radiation generating unit and the subject. The interval ensuring unit is detachably mounted on the collimator unit and is capable of being mounted at different rotational positions about an axis, which passes through a center of a diaphragm of the collimator unit and extends in the direction of an optical axis of the radiation, as a central axis.

Abstract: A CT apparatus includes an annular frame that rotates around a subject positioned in a bore, three columns that hold the frame to be rotatable and movable up and down in a vertical, an elevation mechanism that moves up and down the frame, and a rotation mechanism that rotates the frame. A radiation source and a radiation detector are attached to the frame at positions facing each other. The frame has a width smaller than a width of the radiation source and the radiation detector in a height direction over a whole periphery. An imaging controller performs control for operating the elevation mechanism in response to a return instruction from an operator to move the frame to a retreat height position set at a position of a highest point in an elevation range of the frame on an upper end side of the columns. The imaging controller performs control for operating the rotation mechanism in response to the return instruction from the operator to rotate the frame to a position of 60° that is a first rotation position where the radiation source overlaps the columns.

Abstract: A radiation detector includes a support table, a sensor panel, a fixing member, and a contact member. An attachment surface having an arc surface shape is formed in the support table. The sensor panel has an imaging region in which a plurality of pixels detecting radiation are two-dimensionally arranged. A first surface of the sensor panel is attached to the attachment surface following the arc surface shape. The fixing member partially fixes the first surface to the attachment surface. The contact member comes into contact with a second surface of the sensor panel which is opposite to the first surface to suppress the lifting of the sensor panel from the support table.

Abstract: An acquisition unit of a console acquires a first radiographic image and a second radiographic image. The first radiographic image and the second radiographic image are radiographic images which are output from a radiation detector by directing a radiation source to emit first radiation and second radiation in order to perform a moving image capture mode that continuously acquires a radiographic image required for the display of a moving image according to a preset frame interval. A receiving unit receives a request signal to request the generation of an energy subtraction image referred to for diagnosis. A generation unit generates the energy subtraction image in a case in which the receiving unit receives the request signal.
