Abstract:

BACKGROUND: X-ray image intensifier images are the basement of three-dimensional (3D) model reconstruction based on C-arm two-dimensional (2D) projections. The 3D model reconstruction technology corrected with certain numerical functions can provide enough image information for surgeons during surgery to facilitate surgery.
OBJECTIVE: To explore the 3D model reconstruction technology based on C-arm 2D projections.
METHODS: PubMed database, CNKI database and Wanfang database were retrieved to search papers published between January 1990 to December 2010 about image-guided surgery technology, correction and reconstruction of C-arm 2D images, 3D model reconstruction based on C-arm 2D projections, as well as medical image registration.
RESULTS AND CONCLUSION: 3D model reconstruction based on C-arm 2D projections refers to reconstructing 3D bone models on the basis of 2D projections acquired with a mobile C-arm X-ray machine. 3D reconstructed model contains not only more abundant information about the external anatomy structure of the bone, but also more useful multiple information internal the bone such as bone density and bone strength. The technology contains two main lines: synthetic limited angle X-ray photography of cone-beam; non-rigid registration based on statistical variable model. The technology can be combined with operation navigation technology to establish a surgical navigation system in the future research.
