Interactive visualization of medical data plays an increasingly vital role in clinical diagnosis. Cluttered views, lack of visual cues, etc. Are some of the problems that exist specially when projecting a 3D rendering of a Computed Tomography data on a 2D screen. In this paper we proposed two synthetic visual cues. They facilitate perception by removing visual clutter while maintaining context, directing...
Articulated body animation with smooth skin deformation is an important topic in computer graphics. This paper presents a pipeline that extends articulated body deformation to the volume graphics domain. The pipeline consists of in-vivo volume scans, kinematic joint estimation, volumetric joint weight computation, soft-tissue volume deformation, and direct volume rendering. The result is a fully articulated...
Nowadays, direct volume rendering via 3D textures has positioned itself as an efficient tool for the display and visual analysis of volumetric scalar fields. It is commonly accepted, that for reasonably sized data sets appropriate quality at interactive rates can be achieved by means of this technique. However, despite these benefits one important issue has received little attention throughout the...
We present a new technique for visualizing surfaces from 3D ultrasound data. 3D ultrasound datasets are typically fuzzy, contain a substantial amount of noise and speckle, and suffer from several other problems that make extraction of continuous and smooth surfaces extremely difficult. We propose a novel opacity classification algorithm for 3D ultrasound datasets, based on the variational principle...
