Volumetric rendering is used to visualize volume data from e.g. scientific simulations. Many advanced applications use large gigabyte- or terabyte-sized data sets, which typically means that multiple compute nodes need to partake in the rendering process to achieve interactive frame rates. Load balancing is generally used to optimize the rendering ...
Touchless interaction has recently gained considerable attention by researchers as well as industry. Different domains are interested in implementing this technology in their solutions. Medical visualization has a special interest in this technology due to the sterile conditions in operating rooms. Exploration and detailed inspection of the scanned...

The two most widely used postprocessing 3D tools in clinical practice are volume rendering (VR) and maximum intensity projection (MIP). With the use of current-generation MDCT, these techniques enable accurate characterization of arterial anatomy and pathology in all anatomic regions. Recently, the VR algorithm has been enhanced by the incorporatio...
Hybrid volume rendering algorithms combine techniques of different categories of volume visualization. Volume on Surface (VoS) is a hybrid volume rendering technique that maps volume information to isosurfaces, intending to accelerate the volume rendering process. In this paper, we introduce an improved version of the VoS technique. Furthermore, we...
In this paper, we tackle the challenge of effective Transfer Function (TF) design for Direct Volume Rendering (DVR) of full-color datasets. We propose a novel TF design toolbox based on color similarity which is used to adjust opacity as well as replacing colors. We show that both CIE L*u*v* chromaticity and the chroma component of YCbCr are equall...

We report a rare case of esophageal lung in a neonate who presented with repeated chest infections and respiratory distress. Chest radiograph revealed increased opacification of the right lung with reduced lung volume and air bronchograms. Further evaluation with computed tomography (CT) showed the presence of only left mainstem bronchus at the tra...

Age estimation is commonly of interest in a judicial context. In adults, it is less documented than in children. The aim of this study was to evaluate age estimation in adults using CT images of the sternal plastron with volume rendering technique (VRT). The evaluation criteria are derived from known methods used for age estimation and are applicab...
The generation of 3D city models is a very active field of research. Modeling environments as point clouds may be fast, but has disadvantages. These are easily solvable by using volumetric representations, especially when considering selective data acquisition, change detection and fast changing environments. Therefore, this paper proposes a framew...
