A precise knowledge of geometry is always pivotal to a 3-D X-ray imaging system, such as computed tomography (CT), digital X-ray tomosynthesis, and computed laminography. To get an accurate and reliable reconstruction image, exact knowledge of geometry is indispensable. Nowadays, geometric calibration has become a necessary step after completing CT system installation. Various geometric calibration methods have been reported with the fast development of 3-D X-ray imaging techniques. In these methods, different measuring methods, calibration phantoms or markers, and calculation algorithms were involved with their respective advantages and disadvantages. This paper reviews the history and current state of geometric calibration methods for different 3-D X-ray imaging systems. Various calibration algorithms are presented and summarized, followed by our discussion and outlook.
