Project summary
The Virtual Imaging Platform (VIP) project targets multi-modality, multi-organ and dynamic (4D) medical image simulation. Integrating proven simulation software of the four main imaging modalities (MRI, US, PET and CT), the platform will cope with interoperability challenges among simulators, will address compatibility issues between organ models and will provide transparent access to computing and storage resources.
 
To tackle interoperability issues, the semantics of models and simulation tools will be made explicit. Thiswill be achieved using annotations referring to a set of consistent ontologies describing the organ models, the simulation data processing, the simulation tools and the simulated images. Associated repositories and software interfaces will allow easy experiment design and assisted simulator and model integration. To address the computational challenge, grid technology will be employed. Yet, to cope with reliability issues of large-scale grid systems, VIP proposes to develop a multi-infrastructure execution environment able to use both local computing resources (multi-core servers and clusters) and large-scale grids. No heavy code parallelization is involved though: speed-up will be provided from data and code parallelism only, naturally expressed in simulations.
 
VIP includes a strong application aspect to guarantee the adequacy of the resulting environment with the needs of imaging techniques developers, model designers and image processing researchers. Specifically, VIP includes 4 applicative objectives that will be used to demonstrate this adequacy. These applications are the following: the validation SINDBAD CT simulator (1), the development of a new US sequence for motion detection (2), the modelling of inflammation process from MRI simulation (3) and the evaluation of cardiac segmentation algorithms from multi-modality images (4).
