This paper is focused on the virtual collaborative consultation system which is intended for support of 3D geometrical modelling applications in the field of clinical human medicine. The system allows uploading the CT/MR data and 3D tissue geometry models (prepared in advance). The data define a 3D scene, which allows for viewing of the data and consulting them between technicians and physicians over the medium of computer network. The system is conceived as a three layer client-server architecture. For communication between the server and a client, the HTTPS protocol is used. Test results in Czech republic and the world-wide tests as well confirm, that the system is practically applicable and beneficial.
