X-ray generating apparatus and X-ray fluoroscopyimaging system equipped with the same
First Claim
1. An X-ray generating apparatus, comprising:
- an electron accelerator including an electron acceleration unit, 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 target is surrounded by the shielding structure,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, andthe 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, wherein the planar beams have energy difference therebetween.
