Abstract
This paper describes ongoing research concerning interactive volume visuali zation coupled with tools for volumetric analysis. To establish an easy to use application, the three-dimensional-visualization has been embedded in a state of the art teleradiology system, where additional functionality is o ften desired beyond basic image transfer and management. Major clinical req uirements for deriving spatial measures are covered by the tools, in order to realize extended diagnosis support and therapy planning. Introducing a g eneral plug-in mechanism, this work exemplarily describes the useful extens ion of an approved application. Interactive visualization was achieved by a hybrid approach taking advantage of both the precise volume visualization based on the Heidelberg raytracing model and the graphics acceleration capa bilities of modern workstations. Several tools for volumetric analysis exte nd the three-dimensional-viewing. They are controlled by adequate input dev ices to select locations in the data volume, measure anatomical structures or initiate a segmentation process. Moreover, a haptic interface can be con nected to provide a more realistic feedback while navigating within the thr ee-dimensional-reconstruction. The work is closely related to research in t he field of heart, liver and head surgery. In cooperation with our medical partners the development of tools as presented facilitates the integration of image analysis into the clinical routine. (C) 1999 Elsevier Science Irel and Ltd.
