The experiment started in March 2008 and finished one year later. During this short
time, the platform was upgraded with the new functionalities, the back-end software
was improved and several tests were performed to validate both the BEinGRID
inserted components as well as the solutions provided by the platform using common
radiotherapy software validation tests. Although some of these radiotherapy valida-
tion tests are still under execution at the moment of writing, the benefits of using
Grid has been demonstrated, as will be shown later.
9.2 Description of the Technological Solution
The architecture of e-IMRT after the enhancements were added is illustrated in
figure 9.1 below.

The end users can use both the web based client provided by the project or connect
through their own application calling directly to the services. The computational
back-end infrastructure is completely hidden to them. The expensive computational
work is executed on the local or external Grid resources and managed by GridWay.
The e-IMRT platform is designed following a three layer model (see fig. 9.1).
The first layer can be a thin client based on a web interface, which makes intensive
use of Java and Flash applets. This user interface is used by the medical physicists
to define the parameters of the service request as the maximum or minimum doses
for the optimization, or the reference values for the comparison between dose maps
in the verification. Specific Java applets are used to manage the upload of the needed
treatment and patient's information based on DICOM files. Before leaving the
