This system is well suited for use in operating rooms and mobile use – e.g. on a notebook. The software is permanently installed on the computer and is therefore always available. In addition, data may be saved on a local cache on the computer's hard disk.
The advantage is that in an operating room, data of the cache remain available even if the network connection fails, so that the operation does not need to be interrupted because the images are missing.
On a notebook, intermediate storage on a cache enables mobile use without a network connection – e.g. in the case of a mobile visit.
