It provides multiple options for viewing images in different ways such that it can be used by any user regardless of their experience level or computer skillset (or lack thereof).
The software also allows you access from anywhere so if your doctor isn't available at his/her practice office then they are able see what's going down with patients remotely via video conference! We have been using this system since about 5 years ago when we started our own private radiology practices - I'm sure there has probably always changed some things but overall its worked great!!
