A virtual simulation (VS) system is a software system that enables the delineation of anatomical structures, and the placement of irradiation fields for the purpose of radiation treatment planning, making use of patient's tomographic data, instead of the real patient. Since patient's tomographic data can be communicated between distinct radiotherapy departments, collaborative work on VS, connecting remote health care professionals, becomes feasible. In this paper, an environment enabling real-time collaboration on VS is presented. The environment architecture is based on both offline and online communication of data under a secure framework and can be directly integrated into the infrastructure of a radiotherapy department. The online collaboration relies on the simultaneous execution of all actions at both collaborating sites, and prerequisites the offline communication of the data set on which the collaboration will be performed. Analytical description of the custom-made layered service, which supports the offline communication is given, along with a detailed presentation of the secure management of messages, which enables the real-time collaboration. The technical evaluation of the environment highlights the effectiveness of the proposed methodology, since real-time secure collaboration on VS is achieved.
