Abstract
The present invention provides an X-ray generating apparatus and an X-ray fluoroscopy imaging system comprising the same. The X-ray generating apparatus comprises: an electron accelerator, an electron emission unit, and a target; and a shielding and collimating device, including a shielding structure and multiple collimators arranged in the shielding structure, wherein the collimators are thin gaps extending from the target to an exterior surface of the shielding structure and having an axis transverse an electron beam shooting the target, and at least two collimators forming different angles with the electron beam are arranged on the same side of a plane contains the electron beam shooting the target, and the planes where the collimators locate form angles from 30 degrees to 150 degrees with the electron beam shooting the target, to draw out planar beams having different draw-out angles, each having uniform intensity distribution in its respective plane.
