摘要： A computer-implemented method for the determination of the optimal image viewing direction of an asymmetrical object is included. The method generates a 3D surface reconstruction of the object from 2D images of the object obtained from different perspectives. A point of interest can be specified in at least one of the used 2D images and an area of interest can be specified in the object where the point of interest lies within. A plane containing view directions with reduced foreshortening for the specified area of interest is generated and a 3D point corresponding to the specified point of interest is determined on the 3D surface reconstruction of the object. At least one particular view direction corresponding to the 3D point and located with the identified plane is considered as the optimal image viewing direction of the asymmetrical object. A corresponding apparatus and computer program are also disclosed.

摘要： Method for quantitative analysis of a tree or part of a tree of recursively splitting tubular organs, the method comprising the following steps:—providing a 3D model of said tree or part of said tree, such 3D model giving a representation of the surface of the lumen wall of the tubular organs forming the tree or part of the tree;—defining the 3D centrelines of said tree or part of the tree;—identifying the branches of the tree;—identifying N-furcations of the tree or part of the tree, an N-furcation being a part of the tree where a proximal tubular organ branches into two or more distal tubular organs, further comprising the step of:—dividing, independently from the modality used for obtaining the 3D model, each branch in one or more regions, such regions being of two different types, named single vessel region and splitting region, different cross-section surfaces being defined in such regions, wherein the splitting regions can exist at the proximal side of a branch as well as at the distal side of said branch and each N-furcation comprises the distal splitting region of a branch and the proximal splitting regions of the N branches directly distal to said branch. A corresponding apparatus and computer program are also disclosed.
