The present disclosure relates to methods and systems for calibrating an X-ray apparatus. The X-ray apparatus may include an X-ray detector and a collimator. To calibrate the X-ray apparatus, the methods and systems may include moving the X-ray detector from a first position to a second position along a first axis of a coordinate system, wherein the first position is under a scanning table, and the second position is outside the scanning table; moving the collimator to align the collimator with the X-ray detector at the second position; determining one or more parameters; and determining a second value of the first encoder when the collimator is aligned with the X-ray detector at the first position based on the one or more parameters.

A radiation imaging system includes a setting information storage that stores setting information to be used for radiation imaging, a setting information backup unit configured to back up the setting information stored in the setting information storage, and an operation control unit configured to restore, in a case the setting information storage has failed, the setting information in the setting information storage based on the setting information backed up in the setting information backup unit.

The present disclosure relates to systems and methods for taking X-ray images. The method may include obtaining reference data associated with an object, the reference data including at least one of height data or historical data. The method may also include determining at least one of a start point or an end point of an imaging region associated with the object based on the reference data. The method may further include causing to take an X-ray image of the imaging region based on at least one of the start point or the end point.

A medical image diagnostic system of an embodiment includes a medical image diagnostic apparatus and processing circuitry. The medical image diagnostic apparatus moves on a floor and performs scanogram imaging or main scan imaging. The processing circuitry is configured to acquire a scan protocol to be executed in the medical image diagnostic apparatus, specify a movement range of the medical image diagnostic apparatus on the basis of the scan protocol, acquire information on an area including at least the movement range, and detect or predict presence or absence of an interfering object in the movement range on the basis of the information.

The present disclosure discloses a medical imaging device including a gantry and a first C-arm having an imaging chain. The gantry includes a first supporting arm connecting the first C-arm, a base, a second C-arm connecting the base, and a second supporting arm connecting the second C-arm. The first C-arm may be moveable along the first supporting arm and the second supporting arm may be movable along the second C-arm.

A medical image diagnosis apparatus according to an embodiment of the present disclosure includes: a gantry, one or more columns, a processing circuitry, and, and a supporting and moving mechanism. The gantry includes an imaging system related to imaging a patient. The one or more columns are each configured to support the gantry so as to be movable in a vertical direction. The processing circuitry generates an image on the basis of an output from the imaging system. The supporting and moving mechanism is configured to support the patient from underneath, while being installed so as to be movable in a direction intersecting the moving direction of the gantry. The processing circuitry controls the moving of the supporting and moving mechanism.

A positioning device for a mobile x-ray detector, an x-ray device containing such a mobile positioning device, and a method mutually align a mobile x-ray detector and an x-ray emitter in relation to one another. In order to enable exact mutual alignment or positioning of the mobile x-ray detector in relation to the x-ray emitter, a positioning device is used for a mobile x-ray detector. The positioning device contains at least one marker and/or at least one sensor for determining the position and/or the orientation of the positioning device and contains a number of connection elements for establishing a mechanical connection between the positioning device and the mobile x-ray detector.

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.

An imaging apparatus includes a camera to capture a camera image of a target disposed on an examination table; an X-ray source to generate and radiate X-rays; a memory to store imaging protocols; a display; and a controller. The controller is configured to receive information regarding a selection of an imaging protocol, identify a position of an imaging region of the target based on the camera image, the imaging region corresponding to the selection of the imaging protocol and the camera image being acquired with the examination table at a first distance from the X-ray source, control the display to display the camera image of the target and an indicator indicating the imaging region on the camera image based on the identified position, and control the X-ray source to radiate the X-rays toward the target disposed on the examination table at a second distance from the X-ray source.

The present disclosure discloses medical imaging devices and suspension gantries thereof. An example medical imaging device includes a suspension gantry and a rotatable C-arm which is connected with the suspension gantry and provided with an imaging chain. The suspension gantry includes a suspension base, a first rotating arm configured to be connected to the suspension base and rotatable around a first axis, and a second rotating arm configured to be connected to the first rotating arm and rotatable around a second axis. The rotatable C-arm is configured to be connected with the second rotating arm and be rotated around a third axis.
