Abstract:
Disclosed are calibration assembly and calibration method of calibrating geometric parameters of a CT apparatus. The calibration assembly includes at least one calibration unit each including a plurality of calibration wires, and the plurality of calibration wires are arranged regularly in a same plane. The calibration assembly is easy to be processed and can be used to calibrate geometric parameters of a CT apparatus, and the calibration operations are simple and easy to be implemented.
