   Sammanfattning : Medical imaging is an important part of the clinical workflow. With the increasing amount and complexity of image data comes the need for automatic (or semi-automatic) analysis methods which aid the physician in the exploration of the data. LÄS MER

5. 4. Direct Volume Haptics for Visualization

   Författare :Karljohan Lundin Palmerius; Anders Ynnerman; Matthew Cooper; David Ebert; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haptic Visualization; Volumetric Data; Haptic Primitives; Shape Representations; Time-varying Data; Computer engineering; Datorteknik;

   Sammanfattning : Visualization is the process of making something perceptible to the mind or imagination. The techniques for producing visual imagery of volumetric data have advanced immensely during the last decades to a point where each produced image can include an overwhelming amount of information.
