The image controller includes a detection processing unit configured to detect both a marker for indicating a position of a predetermined target object to be indwelled in a body of a subject and a device to be placed in the body of the subject separately from the predetermined target object, in the generated X-ray image. The image controller includes a composition processing unit configured to generate the composite image by superimposing the plurality of X-ray images based on the detected marker and the detected device.

An imaging position correction application introduction support system is provided with a storage unit and a display unit. The imaging position correction application introduction support system is configured to cause the storage unit to store at least one of the number of times the imaging position correction application was used and a degree of correction when the relative position of the X-ray irradiation unit with respect to the specific site of the subject was corrected by the imaging position correction application, as the tentative use information on when the imaging position correction application is tentatively used. The display unit displays the information based on the tentative use information.

An X-ray imaging apparatus is provided with an X-ray source, a detector, a C-shaped arm, a hose for accommodating wiring, the hose including a base side portion and an opposite side portion, a base including a C-shaped arm support portion and a hose attachment portion to which the base side portion is rotatably attached, a biasing member for biasing the base side portion of the hose to rotate about the hose attachment portion in the first rotation direction outwardly away from the C-shaped arm, and an image processing unit.

The present application provides an X-ray imaging system and a collision prevention method therefor. The X-ray imaging system includes a tube device, at least one sensor, and a controller. The tube device is capable of moving to a preset position so as to emit an X-ray. The at least one sensor is mounted on at least one surface of the tube device. The at least one sensor is configured to acquire a feedback signal within a preset sensing region. The controller is connected to the at least one sensor and the tube device, and the controller includes a determination module and a control module. The determination module is configured to determine, on the basis of the feedback signal, whether an obstacle is present in the preset sensing region and acquire position information of the obstacle. The control module is configured to control motion of the tube device on the basis of the position information of the obstacle.

Three dimensional x-ray imaging systems are described in this application. In particular, this application describes a 3D dental intra-oral imaging (3DIO) system that collects a series of 2D image projections. The x-ray imaging system comprises a housing, an x-ray source attached to a articulating or motion gantry configured to move the source within the housing to multiple positions, an x-ray detector array located on an opposite side of an object to be imaged from the x-ray source, where the detector array is synchronized with the x-ray source to capture 2D images of the object when the x-ray source is located in multiple imaging positions, and a processor configured to accept the 2D images and reconstruct a 3D image. The multiple imaging positions can be located on a plane substantially parallel to the x-ray detector array. Other embodiments are described.

A radiotherapy apparatus for the delivery of an energetic beam to a target tissue in a treatment zone, including: a rotatable gantry for rotating the end of a beam delivery system about a circle centered on an isocentre and normal to an axis of rotation Z1 of the gantry, the path between the end of the beam delivery system and the isocentre defining a central beam axis Z2 at every rotation angle of the gantry about the axis of rotation Z1; an imaging ring having a central bore and an imaging system for acquiring images of a patient in an imaging zone of the imaging system, wherein the imaging ring is located in the radiotherapy apparatus such that its imaging zone intersects the axis of rotation Z1 of the gantry, and wherein the imaging ring is mechanically coupled to the rotatable gantry through a mechanical structure.

A radiographic imaging system may be deployed in an ICU unit of a medical facility that may benefit from isolating patients and health care providers. The radiography system provides a plurality of patient beds each having a digital radiographic detector positioned therein. An x-ray source is operable to be selectively positioned relative to each of the patient beds using a remote control system. The remote control system also controls firing of the x-ray source.

An X-ray device for carrying out X-ray scans is configured for a simplified procedure. The X-ray device has an image receptor which operates in conjunction with an X-ray generator to carry out X-ray scans of a patient, and a patient table. A tabletop of the patient table which is used to position the patient during the X-ray scans, is immovable in the table plane. Instead, the image receptor is disposed in a longitudinally and transversely movable manner relative to the tabletop parallel to the table plane.

A method for controlling the movement of an X-ray source via a suspension device includes obtaining, during a movement of the suspension device along the rail, a first speed of the suspension device at the first reference point. The first reference point may correspond to a first target position. The method may also include determining whether the first speed of the suspension device at the first reference point is less than a threshold speed. In response to a result of the determination that the first speed of the suspension device at the first reference point is less than the threshold speed, the method may further include actuating a control device to move the suspension device to the first target position.
