Survey of See Through Technique in Computer Aided Surgery

The application of see through technique in computer aided surgery is a hot research topic at present. In this article, firstly, the concept of see through is introduced, and the necessity of its application in computer aided surgery is also emphasized. Secondly, the state of arts of see through technique is discussed systematically in computer aided surgery. Thirdly, the research contents of see through technique are summarized into three parts, including registration of medical imaging data, parameter estimation of see through model, and depth perception, which are all explained in details. Fourthly, two standard systems based on see through technique are addressed in this paper. Finally, through the analysis on technique, human factor and clinic applications, further research questions and possible directions in the future are proposed.
