H. Evers et al., Extending a teleradiology system by tools for visualization and volumetricanalysis through a plug-in mechanism, INT J MED I, 53(2-3), 1999, pp. 265-275
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
