The MedIGrid PSE in an LCG/gLite environment

In this paper we are concerned with improvements and enhancements of a medical imaging grid-enabled infrastructure, named MedIGrid, oriented to the transparent use of resource-intensive applications for managing, processing and visualizing biomedical images. We describe an implementation of the MedIGrid PSE in an LCG/gLite environment. We'll mainly focus on how to exploit the features of the new middleware environment to improve the efficiency and the services reliability of the PSE, further, some comments will be devoted to how to modify, extend and/or improve the underlying numerical components.
