Due to the computational and real-time display update requirements of virtual reality interfaces, the complexity of organ and tissue surfaces which can be displayed is limited. In this paper, we present two new algorithms for the production of anatomic surface models containing a pre-specified number of polygons from patient- or subject-specific volumetric image data sets. The advantage of these algorithms is that they efficiently tile complex surfaces with a specified number of polygons selected to optimize the trade-off between surface detail and real-time display rates. Surface detail is preserved by extracting key shape features from the segmented objects, which adaptively constrains the model tilers. To illustrate the utility of these models, we present an overview of their application in computed endoscopy and surgery planning as developed in the Virtual Reality Assisted Surgery Program (VRASP) in the Biomedical Imaging Resource.","PeriodicalId":413660,"journal":{"name":"Proceedings of 1997 International Conference on Shape Modeling and Applications","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131339377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems are cellular networks with minimum incidence numbers (D+1 edges incident on a vertex in D-dimension). In the literature such systems are known as froths since the soap froth is the archetype of these structures. They present a method where the structure of froths is analyzed as organized in concentric layers of cells around a given, arbitrary, central cell. A simple map gives, by recursion, the number of cells in each layer. The map has one parameter, given as a function of the average topological properties of the cells in the neighbouring layers. From the behaviour of the number of cells per layer with the topological distance, one obtains the curvature of the space tiled by the froth. By using the map it is therefore possible to characterize the shape of the manifold tiled by the froth in term of the topological arrangements of its tiles. In two dimensions, they propose a method to deduce the Gaussian curvature of surfaces from a set of sampled points. In three dimensions, they use the map to investigate the freedom in constructing disordered Euclidean cellular structures. Among the closed packed structures, they find the average shape of the cells that maximize this freedom in filling space.","PeriodicalId":413660,"journal":{"name":"Proceedings of 1997 International Conference on Shape Modeling and Applications","volume":"417 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117317588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper reviews one such tool that has recently been designed for the analysis of corresponding biological outlines of similar shape, such as those that arise from organ or tissue boundaries in medical images. The analysis is a hybrid of two morphometric tools, Procrustes analysis and the thin-plate spline, the properties of which are already well-understood separately. The thin-plate spline optimizes one shape metric, the Procrustes methods another. Their combination permits the averaging of groups of outlines, the rigorous display of sample variation around these averages in full detail, and rigorous multivariate statistical detection and testing of hypotheses linking those patterns to their putative causes or effects. The new tool is demonstrated using outlines of the corpus callosum (connection of the cerebral hemispheres) in mid-sagittal images of 12 normal human brains and 13 brains of schizophrenics.","PeriodicalId":413660,"journal":{"name":"Proceedings of 1997 International Conference on Shape Modeling and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125822705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
