Attitude adjustment structure, conveying device, radiation imaging system

An attitude adjustment structure, applied in a radiation imaging system, comprising:

• a base body, arranged in an X direction, the base body having a bearing surface, and the bearing surface being configured to place a detected object;
• a first adjustment assembly, arranged on the base body, and configured to drive the detected object to deviate around a Y direction on the bearing surface and drive the detected object to move in the X direction;
• and
• at least one second adjustment assembly, arranged on the base body and configured to drive the detected object to rotate around a Z direction,
• wherein the first adjustment assembly and the at least one second adjustment assembly are configured to perform a deviating adjustment on the detected object, so that a main beam surface of a light beam generated by a ray machine in the radiation imaging system is parallel to a detected layer surface of the detected object.
