Duration: 1999-2000
In the GALENOS project a European competence network via satellite, dedicated to telemedical applications, has been realised. Owing to the participation of industrial partners in integrating the communication network and getting satellite transmission capacity available, several telemedical services (e.g. offline access to archived data, live consultation of experts, tele-teaching, etc.) have become available in a unified and low-cost technology. This possibility to get support from external experts, the improvement of the precision of the surgical treatment, and last but not least, online documentation and hence improved analysis of the available data on a patient, contributes to a continuous improvement in treatment and care of patients.
The trans-European communication network over satellite provides various collaborative services and applications, avoiding the use of specific technologies, thus promoting a wide availability. Furthermore, the network exhibits inter-operability with previously existing telecommunication networks. The network offers up to 2 Mbit/s interfaces with satellite link and covers at the moment a total of 14 clinics in Bulgaria, France, Germany, Greece, Italy and Tunisia. Access to the local LAN at each site is provided for the exchange of patient data, medical images, videoconferencing, etc. Substantial reactivity and technical flexibility allow treatment protocols, adapted to the patient's pathology, in the shortest time.
WinVicos (Wavelet-based interactive
Video communication system) has been designed for the medical applications using
GALENOS. Beside the main user interface up to four video windows can be displayed
on the user's desktop (Fig. 4). WinVicos runs on a telemedical workstation (PC)
called WoTeSa (Workstation for Telemedical applications via Satellite)
For video compression WinVicos employs a hybrid speed-optimised wavelet-codec.
This codec is based on the concepts of Partition, Aggregation and Conditional
Coding, therefore called PACC (Patent DE 197 34 542 A1, Deutsche Telekom, Darmstadt).
The wavelet-codecs have no blocking artefacts like the DCT-based H.261 and MPEG-4
codecs. Thus, the image quality is much better and there is no need for a deblocking
filter. There is no complex motion estimation, so that a small bandwidth (up
to 1 Mbit/s) is sufficient for typical medical applications: slow lateral motion,
observation in the z-direction, etc..
After the final audit this project was classified as highly successful by the European Commission.
