Abstract: A radiation irradiation apparatus that is configured to independently travel from a decubitus table on which a subject can be placed, the radiation irradiation apparatus including: an attachment portion that allows the radiation irradiation apparatus to be attached to and detached from the decubitus table; a radiation irradiation portion capable of emitting radiation to the subject; a holding portion that is provided at a distal end portion thereof with the radiation irradiation portion and that holds the radiation irradiation portion to be displaceable; and a restriction mechanism that restricts displacement of the holding portion, in which the radiation irradiation apparatus is attached to the decubitus table through the attachment portion to release restriction of the displacement in the restriction mechanism.

Abstract: The radiography unit includes: a wheel portion including a first wheel movable in a first direction by rotation, and a second wheel arranged circumferentially in a rotation direction of the first wheel and movable in a second direction different from the first direction by rotation; a brake mechanism configured to restrict the rotation of the first wheel; and an operation unit configured to receive an operation of changing a state of restriction of the wheel portion by the brake mechanism, the operation being to set a movement direction of the wheel portion to one direction, in which, in a case in which the rotation of the first wheel is restricted by the brake mechanism in response to an operation on the operation unit and movement in another direction intersecting the one direction is restricted, movement in the one direction is enabled by the rotation of the second wheel.

Abstract: An overtube includes an overtube body and a tubular gripping part that is connected to a proximal end side of the overtube body and that has an insertion port which communicates with an insertion pipe line. In cross-sectional view that is viewed from a direction orthogonal to a central axis direction of the gripping part of the overtube, at least a part of an outer peripheral surface of the gripping part has a shape formed by standardization.

Abstract: A radiography system includes a radiation source unit and a panel unit. The radiation source unit includes a radiation emitting unit and a radiation source base part. The panel unit includes a panel that detects radiation, and a panel base part. A floor surface is defined as a projection surface, and a projection region of the radiation source base part and a projection region of the panel base part have a common shape. The radiation source unit and the panel unit can be disposed in a close state where the floor surface is defined as a projection surface and at least one of a projection region of the radiation source unit and the projection region of the panel base part or a projection region of the panel unit and the projection region of the radiation source base part at least partially overlap with each other.

Abstract: A radiography system includes a decubitus table and a radiation source unit that is configured to be independently movable from the decubitus table and includes a radiation source. The radiation source unit is capable of being attached to and detached from the decubitus table, and has an attachment portion that supports at least a part of a weight of the radiation source unit in a state in which the radiation source unit is attached to the decubitus table. The decubitus table has a guide mechanism that guides a movement of the radiation source unit attached through the attachment portion.

Abstract: A radiography system includes: a radiation source unit; a panel unit; and a processor. The radiation source unit includes, a radiation emitting unit, a radiation source base portion that supports the radiation emitting unit and includes a radiation source traveling mechanism for performing a traveling movement, and a first detection unit provided at the radiation source base portion. The panel unit includes, a panel that detects radiation, a panel base portion that supports the panel and includes a panel traveling mechanism for performing a traveling movement, and a second detection unit provided at the panel base portion. The radiation source base portion and the panel base portion have a common shape. The processor controls a relative position or posture of the radiation source unit and the panel unit on the basis detection results of the first detection unit or the second detection unit.
