The primary goal behind the system presented in this paper is to investigate the efficacy of using virtual reality (VR) for showcasing sizable medical equipment. Specifically, we focused on a mobile magnetic resonance imaging (MRI) scanner mounted on a truck trailer. The latter is integral to the mobile MRI setup and must be presented as part of the immersive experience. Therefore, we not only have to depict the medical apparatus but also provide the means of understanding its surroundings. This is especially important to radiologists and other medical personnel to ascertain if a given mobile medical facility fulfills their needs and wants. Furthermore, despite such MRI devices being designed for mobility, their long-distance transportation can be time-consuming, troublesome and expensive. Therefore, we can observe the need for showcasing such mobile MRI units without additional cost and burden related to transportation. To achieve this, we designed an immersive environment in which the users can interact with the real-life scale 3D model of a mobile MRI. In addition, we also verified the usability and expressiveness of our system using established heuristical approaches.
