1. A scanning apparatus, including a gantry, a controller, a C-shaped arm, a radiation source, and a detector, wherein
the radiation source and the detector are arranged at both ends of the C-shaped arm,
the C-shaped arm is connected to the gantry, and
the controller is configured to control a motion of the gantry to drive the C-shaped arm to move so as to scan a target object,
wherein under the control of the controller, the radiation source at one end of the C-shaped arm is configured to move in a first direction while performing a circular scanning motion, the first direction forms a first included angle with a perpendicular line of a circumferential plane formed when the radiation source has a circular motion, and the first included angle is smaller than a preset threshold.
