Summary
Objective:
The goal of this work is to improve the usability of a non-rigid registration software
for medical images.
Method:
We have built a registration grid service in order to use the interactivity of a
visualization workstation and the computing power of a cluster.
On the user side, the system is composed of a graphical interface that interacts in
a complex and fluid manner with the registration software running on a remote cluster.
Conclusion:
Although the transmission of images back and forth between the computer running the
user interface and the cluster running the registration service adds to the total
registration time, it provides a user-friendly way of using the registration software
without heavy infrastructure investments in hospitals. The system exhibits good performances
even if the user is connected to the grid service through a low throughput network
such as a wireless network interface or ADSL.
