A Grid Service for the Interactive Use of a Parallel Non-Rigid Registration Algorithm

In order to improve the usability of a non-rigid registration software running in parallel on a cluster of workstations, we have build a registration grid service. The system is composed of a graphical user interface on the user side that interacts in a complex and fluid manner with the registration software running on a remote parallel computer. 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 simple 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 wireless network interface or ADSL.
