| 英文摘要: |
| An automatic method is proposed to solve the registration problem, which aligns a single 2D fluoroscopic image to a 3D image volume without demanding any additional media like calibration plate or user interactions. First, a mathematic projection model is designed which can reduce the influence of projection distortion on parameter optimization and improve the registration accuracy. Then, a two stage optimization method is proposed, which enables a robust registration in a wide parameter space. Furthermore, an automatic registration framework is proposed based on the Fourier-Mellin robust image comparison descriptor. Experimental results show that the registration method has a high accuracy with average rotation error of 0.6 degree and average translation error of 1.4mm. |
