X-RAY IMAGING DEVICE, X-RAY DETECTOR, AND X-RAY IMAGING SYSTEM

SAMSUNG ELECTRONICS CO., ...

1. An X-ray imaging apparatus comprising:an X-ray radiation device configured to emit X-rays;
a receptor into which a first X-ray detector configured to detect the emitted X-rays is inserted;
an X-ray detector sensing interface configured to detect whether the first X-ray detector has been inserted into the receptor, acquire first identification information of the first X-ray detector inserted into the receptor, and generate first position information indicating that the first X-ray detector has been inserted into the receptor;
an output interface configured to output information about the first X-ray detector; and
a controller configured to control the output interface to output the first position information and the first identification information,
wherein the first identification information is identification information set by a workstation of an X-ray imaging system including the X-ray imaging apparatus,
wherein the first X-ray detector is further configured to output an optical signal corresponding to the first identification information,
wherein the X-ray detector sensing interface comprises an optical sensor configured to detect the optical signal, and
wherein the controller is further configured to acquire the first identification information based on the detected optical signal.

SLIDING ARRANGEMENT FOR MOBILE TOMOSYNTHESIS X-RAY SYSTEM

AGFA NV, Mortsel (BE)

1. A sliding arrangement for mounting an X-ray source assembly on a supporting arm of an X-ray unit, the sliding arrangement comprising:a linear track including a linear rail supported by a structure that mounts the sliding arrangement onto the supporting arm;
a carriage slidably mounted and movable along a length of the linear rail, the carriage including a pivotable mounting interface that mounts the X-ray source assembly;
a tilting actuator that adjusts an angle between the carriage and the pivotable mounting interface based on a position of the carriage along the linear rail,
and that includes a pin configured to be guided by a guiding slit to actuate a crank fixed to a rotation axis of the pivotable mounting interface during linear movement of the carriage along the linear rail; and an angle adjusting gearing that adjusts an angle between the guiding slit and the linear rail; wherein
the angle between the carriage and the pivotable mounting interface is adjustable so that a center axis of an X-ray beam generated by the X-ray source assembly mounted on the carriage intersects with an isocenter at a distance d from a center of the sliding arrangement at any position of the carriage along the linear rail.
