In an X-ray dose management system, a dental radiograph device includes an imaging condition setter, an output information creator, and an information communicator that sends the output information to a wireless tag. An X-ray imaging element includes an X-ray image information obtainer and a wireless tag. An information reading device includes an output information reader and an information communicator that sends the read output information to an information terminal. The information terminal includes a patient information retriever that retrieves patient information from a patient information storage, a communicator that receives the output information, and an output information processor that records the output information and the patient information in association with each other in the patient information storage.

A radiation imaging system comprises a sensor unit of a radiation imaging device, detecting an incident radiation R irradiated from a radiation generator; an arithmetic unit calculating an accumulated dose of the radiation detected by the sensor unit; and an imaging control unit outputting an irradiation stop signal for stopping the irradiation of the radiation R to the radiation generator when the accumulated dose reaches a threshold or more, wherein the imaging control unit sets the threshold based on a dose rate of the radiation R determined based on a relationship between the accumulated dose and a time, and a delay time from a time of outputting the irradiation stop signal to a time of stopping the irradiation of the radiation of the radiation generator.

Disclosed is a patient positioning assembly for orientating a patient with respect to a radiation source. The patient positioning assembly includes a translatable member movable in a vertical direction between a vertically downwards first position and a vertically upwards second position. The patient positioning assembly further includes a patient support assembly mounted to the translatable member and adapted to rotate relative to the translatable member about a vertical axis. The patient support assembly is configurable between a first orientation, which sustains the patient in a seated position, and a second orientation, which sustains the patient in a generally standing position.

A method is provided for running a collision protection system for a medical operating device, which has a patient bed for a patient to be operated on, an image recording device having at least one movable image recording component for recording image data of the patient during the operation, and an assistance robot having a movable assistance component which during the operation is situated at least temporarily inside the patient and/or is coupled in terms of movement to an instrument situated inside the patient. In the method, an item of criticality information is determined which describes the criticality of possible collisions of components of the operating device and/or movements of the patient with regard to the interaction of the assistance robot with the patient. Depending upon the criticality information, when a criticality criterion indicating a raised criticality, (e.g., a criticality exceeding a threshold value), is met, a safe mode of operation of the collision protection system is activated, which meets higher safety requirements than a normal mode of operation.

A radiological apparatus including: a gantry encapsulated within a cover, a patient platform, and two radiation sources with imaging directions orthogonal to each other, sliding vertically to perform vertical scanning of a patient standing on the platform. The gantry cover top view is L shaped, each radiation source being located outside the gantry cover, inside the angular sector of the L, and is encapsulated within a cover sliding vertically with the radiation source it encapsulates. The radiological apparatus also includes: a first security device stopping the vertical scanning, when it detects a patient body part going outside a first predetermined area, to avoid collision with the vertically sliding radiation sources covers, and a second security device stopping the vertical scanning, when it detects an object or a person external to the radiological apparatus within a second predetermined area, to avoid collision with the vertically sliding radiation sources covers.

A method is for providing collision information. In an embodiment, the method includes acquiring first position data relating to an outer contour of an object, via at least one measuring device arranged on a gantry of a medical imaging device; receiving second position data relating to an inner contour of an opening of the gantry and/or an outer contour of the gantry; receiving movement data relating to relative movement between the gantry and the object; calculating the collision information relating to a collision of the object and the gantry, based on the first position data, the second position data and the movement data; and providing the collision information.

A computed tomography device includes, in an embodiment, a gantry including a tunnel-shaped opening, an examination object being introducible into the tunnel-shaped opening for an examination via the computed tomography device; and a radiation protection apparatus to cover the tunnel-shaped opening, the radiation protection apparatus including a first connector and the gantry includes a second connector. In an embodiment, a detachable connection is formable via the first connector and the second connector, to counteract removal of the radiation protection apparatus from the tunnel-shaped opening.

A device for implementing a latching function of an adjustment axis of an X-ray C-arm comprises at least two magnetic bodies and two components of the adjustment axis that are movable relative to one another. A first component of the two relatively movable components of the adjustment axis is operatively connected to a magnetic body of the at least two magnetic bodies. A second component of the components of the adjustment axis movable relative to one another is a component of the X-ray C-arm system and the second magnetic of the at least two magnetic bodies is operatively connected to this component.

A radiation protection material (10) is arranged between at least two layers (21, 22) of at least one plastic-containing element in order to produce a radiation protection element. At least part of the gas present between the at least two layers (21, 22) is removed. The at least two layers (21, 22) are connected with each other.
