<P>PROBLEM TO BE SOLVED: To provide an axis alignment method and an X-ray imaging system which alleviate burden imposed upon an operator. <P>SOLUTION: In the axis alignment method and the X-ray imaging system, a magnetic field generator 29 of an X-ray tube 3 generates X-ray by deflecting an electronic beam emitted from an anode 25 to irradiate a predetermined position of a cathode 31 with the same. When the magnetic field generator 29 is operated, a focal position that generates X-ray moves. By using it, axis alignment is carried out to align an X-ray axis, which is the central axis, of the X-ray focused on the center of a detecting surface 5a of an X-ray detector 5 when arranging the X-ray tube 3 or the like. Because axis alignment can be carried out from a location, for example, that is far from an X-ray shielding system, X-ray exposure can be reduced. In addition, axis alignment is carried out easily and thus steps for axis alignment can be reduced. As a result, burden imposed on an operator is alleviated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
