A "Collaboratory" is a lightweight application component allowing project teams to collaborate and share data and insight while distributed over a network, using intuitive visual navigation techniques. The innovation can be summarised as the integration network technology used in collaborative games with 3D data navigation technique based on a low-Ievel, fine-grained, customisable "atomic" visualization component infrastructure. In this paper we have focused on 3D medical imaging tools describing a Collaboratory implementation of a "VolumeViewer". This paper also a blueprint to inform researchers and software engineers about the possibility to extend existing visualisation applications to support collaboration, making it easier to" collaboratize " visualization applications based on Microsoft's DirectX class library.
