A breast imaging apparatus includes a radiation source that irradiates a breast of a subject with radiation, a radiation detector that detects the radiation transmitted through the breast to output a radiographic image, an ultraviolet light source that performs irradiation of ultraviolet light, and a controller that controls an operation of the ultraviolet light source. The controller prohibits the irradiation of the ultraviolet light by the ultraviolet light source in a case where a predetermined set condition is satisfied. The controller determines that the set condition is satisfied, for example, in a case where a person is shown in a captured image of a camera.

Radiodiagnostic apparatus and method of operating radiodiagnostic apparatus

A breast imaging apparatus includes a radiation source that irradiates a breast of a subject with radiation, a radiation detector that detects the radiation transmitted through the breast to output a radiographic image, and an ultraviolet light source that performs irradiation of ultraviolet light. The ultraviolet light source irradiates an imaging table, a face guard, a pressing plate, and the like with the ultraviolet light in a case where a turn-on command signal input from an operator through an input device is input.

A mammography apparatus includes: a radiation source that emits radiation to mammae of a test subject; a support part that supports the radiation source to be rotatable around an axis and moves the radiation source to a plurality of imaging positions where incidence angles of the radiation to the mammae are different from each other; a face guard that protects the test subject from the radiation emitted from the radiation source; and at least one pair of arms that is rotatably connected to the face guard at one end thereof, is rotatably connected to a holding part that maintains a stationary state with respect to the rotation of the radiation source at the other end thereof, includes a bending part between the one end and the other end, and is rotatable around a rotation axis that connects the one end and the other end.

Mammography apparatus

Provided is a mammography apparatus capable of reducing an increase in the size of an entire apparatus in a case where a plurality of filters and a mirror are provided. A mammography apparatus includes a radiation source that emits radiation toward an imaging stand, a visible light source that is provided outside an irradiation field of the radiation emitted from the radiation source and emits visible light, a first filter that includes an Rh filter and an Al filter as a plurality of filters that is selectively used according to the kind of imaging, and a mirror part that is provided between the radiation source and the imaging stand, includes a Cu filter used in a case where contrast imaging is performed, reflects the visible light toward imaging stand, and is movable between a position inside the irradiation field and a position outside the irradiation field.

A radiographic imaging device comprising an imaging platform that includes an imaging surface on which a breast of a test subject is to be rested; a radiation irradiation section disposed to face the imaging surface and irradiates radiation at the imaging surface; a main radiation protection portion that is disposed at the side of a region between the radiation irradiation section and the imaging surface and that is adapted to protect the test subject from the radiation; and an auxiliary radiation protection portion disposed at a side portion of the main radiation protection portion, and that is movable between a protecting position, at which the auxiliary radiation protection portion is adapted to protect the test subject, and a non-protecting position, at which the auxiliary radiation protection portion is withdrawn from the protecting position.

Radiographic imaging device and radiography protection unit

The present invention provides a radiation blocking unit including: an attachment member that is attachable between sources and an object table surface to which radiation from a radiation source and visible light from a visible light source are emitted, the sources including the radiation source and the visible light source; a radiation blocking portion, disposed on the attachment member, that transmits the illuminated visible light to an overlapping incidence region on the object table surface in which an incidence region of the radiation and an incidence region of the visible light overlap, and that blocks the irradiated radiation outside the overlapping incidence region; and a visible light blocking portion, disposed on the attachment member, that transmits the irradiated radiation to the overlapping incidence region, and blocks the illuminated visible light outside the overlapping incidence region.
