Reinforcement: physical
quantity is increased in order

VR-based diagnosis – Applicable techniques
False color representation:
a physical quantity (such as
temperature) is visualized
via color coding
Samples: the viewer can
use a measurement sensor
to display the model´s
Selective display: only areas
with certain measurement
values are displayed: problem
zones
Superposition: 2 simulation
results or one test part and a
simulation result are
VR-based
Diagnosis
Comparative presentation:
alternative processes are
shown simultaneously to
detect differences
Subtractive representation:
only the difference between
two alternative processes is
displayed. This makes process
differences even easier to
identify

measurement values. The
sensor may be variable
regarding the measured
quantity.
Sections: the 3D model is
cutted into sections in
order to make the viewer´s
areas of interest clearly
visible

Intraoperative support
9th of October, 2012: At the ARTORG Center
for Biomedical Engineering in Bern, surgical
navigation technology is combined with
augmented reality displays. This technology
makes it possible to map the internal
structure of an organ during an operation.

structure of an organ during an operation.
The new procedure was now used for the
first time in a complex liver operation.
The liver is shown in triplicate: A screen in the
operating room shows 3D computed
tomography (CT) and magnetic resonance
(MRI) scans illustrating the internal anatomy
of the patient's liver. On another screen
endoscopic images of the miniature camera
can be seen and a third screen shows a
combination of both, a superimposed,
reality-enhanced image. All the relevant
information is summarized in a surgical
cockpit on several screens – this method
helps to simplify orientation and make better
decisions.
