A collimation adjustment device for a dual-path orthogonal x-ray source and image detector
By adjusting the screws and washers in synergy, the spatial orientation of the X-ray generator was precisely adjusted, solving the problem of the X-ray beam central axis not being perpendicular to the detector receiving plane. This improved the imaging geometric accuracy and resolution, and resolved the image quality degradation caused by structural errors and elastic deformation.

Abstract
The utility model relates to the field of two -way orthogonal X -ray source especially relates to a kind of collimation adjusting device of two -way orthogonal X -ray source and image detector, including G type arc arm;Still including adjusting screw one, the outer surface of G type arc arm is provided with two fixed frames, the inboard of fixed frame is provided with two fixed plates, fixed plate is fixedly connected with G type arc arm, the inside of fixed frame is provided with X ray generator, and the inside of fixed frame is connected with adjusting screw one in screw thread;The utility model is fixed after X ray generator on frame, by imaging comparison synchronous adjustment adjusting screw one drives adjusting gasket one displacement, adjusting screw two drives adjusting gasket two displacement, until X ray beam projection area and detector receiving plane realize strict alignment, this adjusting mechanism can effectively compensate G type arc arm structure machining error, gravity load elastic deformation and the millimeter level centering deviation caused by screw drive mechanism precision limit.
