Elastic registration of brain images on large PC-Clusters
2001
Future generations computer systems
Preserved Fulltext
Our approach of correcting these deformations is based on an elastic matching of the images. ...
As these requirements are in the range of today's grand challenges, a large PC-Cluster was used to provide the performance demands. ...
In this paper we describe the parallel implementation of our elastic matching algorithm and present performance measurements on a 48 node cluster system. ...
