ROTARY X-RAY COLLIMATOR AND X-RAY IMAGING APPARATUS COMPRISING THE SAME

摘要

A rotary X-ray collimator, which can be installed in a narrow space, and can be easily driven, and an X-ray imaging apparatus including the same are disclosed. According to an embodiment of the present invention, a rotary X-ray collimator comprises: a blocking surface rotating body having a plurality of blocking surfaces, the blocking surfaces each having a transmitting window pre-formed to transmit a portion of an X-ray beam emitted by an X-ray generator, and forming a polyhedron; and a rotating unit rotating the blocking surface rotating body such that a blocking surface selected from among the blocking surfaces is disposed on a path of an X-ray beam. According to an embodiment of the present invention, an X-ray imaging apparatus includes a rotary X-ray collimator adjusting the emitting range of the X-ray beam by transmitting a portion of an X-ray beam emitted by the X-ray generator along with the X-ray generator.
