This paper presents the TENECI (Collaborative tele- neurology) project which allows practitioners to use telecommunication technologies to provide medical information and services for neurological diseases. Specificities of remote neurology are described and the CAliF multimedia platform on which TENECI relies is presented. In the last section we present our implementation of TENECI. This software is composed of several services, such as a DICOM explorer, a DICOM viewer, a security service… Tests performed on this first TENECI release have given good results, and allow us to hope for a large experimentation between French and Swiss hospitals using secured connections.
