The back-end environment consists of 3 major components: the webserver, the communication server and the database. These components are each scalable of several (virtual) servers and can be very easely made redundant . This allows the environment to be scaled for both small radiology practices on 1 server, as large hospitals on multiple servers. Through this scalability the enviroment can also be equipped with one single testserver on which the whole configuration can be tested. The environment integrates easily with the existing infrastructure of the hospital and their IT policies.
