Description
JKU/RISC currently develops in cooperation with Upper
Austrian Research (UAR) the
SEE-GRID software system. SEE-GRID is based on the SEE++
software for the
biomechanical 3D simulation of the human eye and its
muscles. SEE++ simulates the
common eye muscle surgery techniques in a graphic
interactive way that is familiar to
an experienced surgeon. SEE++ is world-wide the most
advanced software for this
purpose; it is used by various hospitals and medical doctors
for surgery training and
planning,
SEE++ deals with the support of diagnosis and treatment of
strabismus, which is the
common name given to usually persistent or regularly
occuring misalignment of the
eyes. Strabismus is a visual defect in which eyes point in
different directions. A
person suffering from it may see double images due to
misaligned eyes. SEE++ is able
to simulate the result of the Hess-Lancaster test, from
which the pathological
reason of strabismus can be estimated. The outcome of such
an examination is two gaze
patterns of blue points and of red points respectively. The
blue points represent the
image seen by one eye and the red pointsthe image seen by
the simulated other eye,
but in a pathological situation there is a deviation between
the blue and the red points.
In SEE++, a third gaze pattern, a measured one (with green
points) of a patient can
be given as input. In this case, SEE++ takes some default
or estimated eye data and
modifies a subset of them until the calculated gaze pattern
of the simulated eye (red
points) matches the measured gaze pattern. This procedure
is called pathology
fitting. The current algorithm is time consuming and gives
only a more or less
precise estimation for the pathology of the patient. Doctors
want to see quickly the
results from such a decision support system, but for
reaching adequate response times
it is not sufficient to use only local computational power.
The goal of SEE-GRID is to adapt and to extend SEE++ in
several steps and to develop
an efficient grid-based tool for Evidence Based Medicine,
which supports the surgeons
to choose the best surgery techniques in case of the
treatments of different
syndromes of strabismus. We approach this goal in three phases:
- We have implemented a parallel and grid-enabled version of
the Hess-Lancaster test
simulation (it is based on the Globus Toolkit at present).
- We are currently developing a grid-based medical database
described for storing and
sorting patient data with gaze patterns and eye data.
- We plan to make a gLite compatible version of SEE-GRID and
then further develop it
on the basis of the higher services of the EGEE-II
middleware (comparedwith the
low-level services of the Globus Toolkit).
- We will work on a parallel grid-enabled pathology fitter
algorithm.
