GEOMETRIC PARAMETER CALIBRATION PIECE AND CALIBRATION METHOD FOR CT DEVICE

摘要

A geometric parameter calibration piece for a CT device The geometric parameter calibration piece comprises at least one calibration unit (10), each calibration unit (10) comprises multiple calibration wires (2), and the multiple calibration wires (2) are regularly arranged in the same plane. The geometric parameter calibration piece is easy to machine, and can calibrate the geometric parameters of a CT device. Further disclosed is a corresponding calibration method, and it is simple and easy to implement a calibration operation.
