Image registration precision verification 2D/3D registration experiments were conducted using spinal models and CT medical images and X-ray images of two patients. For the spinal model, the X-ray image of the spine was rotated clockwise around the z-axis by ten degrees, and ten sets of registration experiments were repeated. Registration experiments were also conducted on the medical images of the two patients.
