    摘要： An imaging system includes a gantry and a compression system coupled to the gantry and rotatable relative to the gantry. The compression system includes a compression paddle, a support platform, and an x-ray receptor disposed below the support platform. An x-ray tube head is coupled to the gantry and includes an x-ray source and a light source. The x-ray tube head is independently rotatable relative to the gantry and the compression system. The light source is configured to generate at least a first light type and a different second light type directed towards the support platform. The second light type being mapped to an x-ray field of the x-ray source, and the generated second light type is based on a tilt angle of the x-ray tube head relative to the support platform and a compression force of the compression paddle.

    摘要： A computed tomography (CT) machine system and a state monitoring method are described. The CT machine system comprises a drum-shaped component, a 3D camera, and a control system. The drum-shaped component comprises a cylindrical body, with the center of the cylindrical body being provided with a hollow portion which is rotationally symmetrical about the central axis of the cylindrical body, a rotating component disposed in the cylindrical body rotating about the central axis, a plurality of trigger marks arranged in the rotating component, and a window provided in the cylindrical body. The 3D camera generates image data that is transferred to the control system, from which the control system determines state data of the CT machine. The 3D camera captures an image of the trigger marks through the window to generate marked image data.

    摘要： Artifacts in a tomographic image of a subject including a cyclically moving object to be treated are reduced. A radiographic imaging device includes: a gantry that is equipped with two sets of radiation sources and detectors which are used in pairs, the gantry rotating the radiation sources and the detectors around a subject; and a reconstruction section that reconstructs a tomographic image of the subject based on multiple projection images generated from output of the detectors. The radiographic imaging device further includes: a phase calculation section; a divide section that divides, on a phase-by-phase basis, first projection image groups of multiple projection images acquired by the first set, and similarly second projection image groups acquired by the second set; and a condition setting section. The reconstruction section reconstructs a tomographic image by use of the first and second projection image groups that are placed in the same phase.

    摘要： An imaging apparatus for use with an imaging device in order to image a subject. The imaging device includes an annular gantry having an opening and a table to accommodate the subject or a portion thereof for imaging. The imaging apparatus includes a platform and a positioning device. The imaging device is mounted to the platform. The annular gantry is in a fixed position relative to the platform. The table is horizontally displaceable relative to the annular gantry. The positioning device supports the platform and is configured to horizontally displace the platform relative to a supporting surface for the subject. The positioning device is configured to position the platform with the imaging device in at least one operational state in such a way that, during a relative movement of the table with respect to the annular gantry, the table remains stationary relative to the supporting surface.

    摘要： By combining a plurality of protective devices (PD), the present invention makes it possible to allow good transmission of primary X-rays and to reduce the strength of scattered X-rays in all directions. The scattered X-rays to be reduced are: those from above and from the sides for an additional shield box 1, which is a PD; and those from below for a high-performance table 2. Furthermore, by combining protective instruments in addition to PDs, it is possible to reduce the strength of scattered X-rays that leak to the sides from a pass-through port of a box due to human body movements during a surgery. Further using composite absorption material in various locations enables lineal energy absorption, with scattered X-rays being weakened. Thus, it is possible to reduce the radiation exposure of the patient and the medical worker and reduce the burden of protection for the medical worker.

    摘要： An x-ray system includes a base component, a table to support a patient in a prone position and defining an opening for a breast of said patient to extend downwards therethrough into an active spatial region, a rotatable x-ray assembly including an x-ray source and an x-ray detector and being configured to rotate at least partially around said active spatial region, and an optical system that includes an optical detector arranged in an optical path to said opening of said table. In one aspect, the x-ray system further includes a radiation-safety interlock device configured to communicate with said optical detector and said x-ray source, allow said x-ray source to be engaged while an object is detected, and disengage said x-ray source otherwise. In another aspect, the optical system includes an optical detector that is optically conjugate with a radiation emission region of said x-ray source.
