Abstract
A method for focusing an X-ray method is provided and the method includes: emitting an electron beam by an electron beam generator; shooting the electron beam onto a target to generate an X-ray beam; and causing the X-ray beam to pass through each collimating channel of a same collimating channel group of a collimator to focus on a focus of the collimating channel group. The collimator includes at least one collimating channel group. Each collimating channel group includes at least two collimating channels. The same collimating channel group has one focus or a plurality of focuses.
