Speaker: Sandro SquarciaNORMA (Network Oriented Radiological and Medical Archive) is an original project to select the best Treatment Planning in radiotherapy. It allows physicians and health physicists, working in different places, to discuss on interesting clinical cases visualizing the same diagnostic images at the same time and highlighting zones of interest (tumors and organs at risk).
NORMA has a client/server architecture in order to be platform independent. Applying World Wide Web technologies, it can be easily used by people with no specific informatic knowledge and it provides a verbose help to guide the user through the right steps of execution. The client side is an applet while the server side is a Java application. In order to optimize execution the project also includes a proprietary protocol, lying over TCP/IP suite, that organizes data exchanges and control messages.
Diagnostic images are retrieved from a relational database or from a standard DICOM (Digital Images and Communications in Medicine) PACS through the DICOM-WWW gateway allowing connection of the usual Web browsers used for the NORMA system to DICOM application using the HTTP protocol. Browser requests are sent to the gateway from the Web server through CGI (Common Gateway Interface). DICOM software translates the requests in DICOM messages and organizes the communication with the remote DICOM Application.
