TLDR
In this paper, a volume visualization technique for generating a 3D visualization image of an internal organ using volume visualization techniques is presented. But this technique is not suitable for the visualization of complex 3D objects.
Abstract
Methods for generating a three-dimensional visualization image of an object, such as an internal organ, using volume visualization techniques are provided. The techniques include a multi-scan imaging method; a multi-resolution imaging method; and a method for generating a skeleton of a complex three dimension object. The applications include virtual cystoscopy, virtual laryngoscopy, virtual angiography, among others.

System and method for organ segmentation using surface patch classification in 2d and 3d images

TL;DR: In this article, a method for segmenting organs in digitized medical images is proposed, where a set of segmented training images of an organ is used to compute a surface mesh having a plurality of mesh cells that approximates a border of the organ, extracting positive examples of all mesh cells and negative examples in the neighborhood of each mesh cell which do not belong to the organ surface.

Specifying search criteria for searching video data

TL;DR: In this paper, a method and apparatus for specifying regions of interest within a two-dimensional view of visual information that comprises a series of frames are described, and search criteria are compared against the stored visual changes to identify a sequence of frames in which the specified visual change occurred within the first region of interest.

Penalized-distance volumetric skeleton algorithm

TL;DR: A refined general definition of a skeleton is introduced that is based on a penalized distance function and that cannot create any of the degenerate cases of the earlier CEASAR and TEASAR algorithms.
