Abstract:
Computer Simulations,like 3D Animations,have gained increasing
importance in medcine and especially in cardiac surgery. Difficult operative
techniques can be easily demonstrated using the virtual 3D reality. Furthermore
it is possible to perform new techniques in cardiac surgery for newsgroups via
the internet.
Methods:
We create virtual scenes of operative situations in 3D virtual
reality. Therefore we use different 3D and 2D graphic programs. In the
beginning we discussed and analysed operative sequences to find out what is
really important. Digital videos and digital photos of coronary bypass surgery
helped us to create our virtual scenes. An Informix universal database is used
as a multimedia repository. This database contains media data of: digital
video, digital photo, VRML-models of cardiac anatomy and virtual 3D reality.
Results:
The Informix universal database allows to use and re-use
mediadatas. This means that the user is able to interact with the system. At
the moment the system contains virtual scenes of aortocoronary bypass grafting.
There is also a VRML-model of the heart integrated in the system.
There are several benefits of virtual reality:
·
Interactive System
·
Different virtual viewpoints
·
Explanation of complex situations
·
Demonstration of "How to do"
·
Learning by viewing
Conclusions:
Virtual reality in cardiac surgery is able to teach very complex
and difficult proceedings in cardiac surgery. Virtual reality helps to
understand difficult operations.
Complete cardiac operations can be presented as interactive
virtual scenes in the next future.
Today our system support a flexible composition, re-use and
presentation of multimedia data in an economic manner. The system is able to
perform cardiac surgery techniques at the state of the art at any time and any
location.
Benefit in Attending
Session:
We demonstrate the benefits of virtual scenes in cardiac surgery
using virtual reality techniques like 3D computer animations.
