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.
