A CPU acquires a distance image which indicates a distance to an imaging target and is captured by a TOF camera using, as an imaging region, a region including at least a portion of a region in which an attachable and detachable member is attached to a mammography apparatus. Further, the CPU acquires reference distance information related to a reference value of a distance between the attachable and detachable member and the TOF camera in a state in which the attachable and detachable member is attached to the mammography apparatus. Furthermore, the CPU determines whether or not the attachable and detachable member is attached to the mammography apparatus on the basis of the distance image and the reference distance information.

Disclosed herein are an X-ray input apparatus capable of exactly reflecting an operator's intention to perform calibration control, an X-ray imaging apparatus including the X-ray input apparatus, and a method of controlling the X-ray input apparatus. In accordance with an aspect of the present disclosure, an X-ray input apparatus comprises a body configured to be accommodated in a holder of an X-ray imaging apparatus. The apparatus also includes a touch sensor disposed on an outer circumferential surface of the body and configured to sense a touch. The apparatus also includes a radiation button disposed on a top of the body and configured to receive a control command from an operator. The apparatus also includes an input controller configured to perform calibration control when the body is accommodated in the holder, thereby deciding a capacitance threshold value of the touch sensor.

Hybrid detection systems and methods for C-arm interventional x-ray systems are provided. The hybrid detection system can have a changeable x-ray detection system that is coupled to an integrated within a C-arm x-ray imaging system. The changeable x-ray detector system can include an energy-integrating x-ray detector, and a photon-counting x-ray detector. The C-arm x-ray imaging system using only one detector at a time to acquire x-ray imaging data.

A mobile medical imaging device that allows for multiple support structures, such as a tabletop or a seat, to be attached, and in which the imaging gantry is indexed to the patient by translating up and down the patient axis. In one embodiment, the imaging gantry can translate, rotate and/or tilt with respect to a support base, enabling imaging in multiple orientations, and can also rotate in-line with the support base to facilitate easy transport and/or storage of the device. The imaging device can be used in, for example, x-ray computed tomography (CT) and/or magnetic resonance imaging (MRI) applications.

A modular X-ray source and method for replacement of such an X-ray source are disclosed. The source is inside a consumable modular enclosure where the entire assembly is swapped out during maintenance. The enclosure covers an X-ray tube, high voltage circuit boards 6 and cooling insulating oil are arranged inside the module enclosure. The enclosure structure includes an X-ray window, connector engagement alignment guide and electrical connectors. The modular X-ray source is used in a multiple source tomosynthesis imaging system where multiple pulsed X-ray sources are utilized. The easy replacement of X-ray tube assembly inside the consumable modular enclosure results in lower maintenance cost and overall reliable X-ray imaging machine. The modular source has potential to increase the machine volume in the field and create new standards for replaceable modular X-ray source.

For gamma ray detection, 3D tiling is made possible by modules that include a gamma ray detector with at least some electronics extending away from the detector as a side wall, leaving an air or low attenuation gap behind the gamma ray detector. The modules may be stacked to form arrays of any shape in 3D, including stacking to form a Compton detector with a scatter detector separated from the catcher detector by the low attenuation gap where the electronics form at least one side wall between the detectors. The modules may be stacked so that the detectors from the different modules are in different planes and/or not part of a same surface (e.g., same surface provided with just 1D or 2D tiling).

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.
