“…Such training has been successfully validated [9,10]. Similarly simulators for various teleoperated procedures, such as eye procedures [11], and arthroscopy (including haptic feedback elements) [12][13][14] are available. Simulation of more complex procedures (in terms of the perceptual environment) is still an active research topic.…”

Details of a low cost augmented-reality system for the simulation of ultrasound guided needle insertion procedures (tissue biopsy, abscess drainage, nephrostomy etc.) for interventional radiology education is presented. The system comprises physical elements; a mannequin, an ultrasound probe and a needle, and software elements; generating virtual ultrasound anatomy and allowing data collection. These two elements are linked by a pair of magnetic 3D position sensors. Virtual anatomy, for image generation, is generated based on full body CT scans of live humans. Details of the novel aspects of this system are presented including; image generation, registration and calibration.

As an important area of computer graphics, realistic image synthesis provides principles and techniques for creating realistic imagery through computations based upon models of real-world objects and behaviors. Facial expression is one of the primary communication means of the human. The ultimate goal of realistic image synthesis is to achieve perfect realism -the synthesized images are visually indistinguishable from their real-world counterparts. This area has widespread applications in industry and scientific research including 3D design, omputer animation, scientific visualization and virtual reality Facial expression synthesis has many useful applications in practice. How to synthesize facial expression images robustly and simply is still a challenging problem. This paper surveys the state of the art in this area.

“…To our knowledge, the human orbit has not yet been modeled through a FE approach. The ocular globe has been studied using a FE model [5] but this model is not appropriate for the exophthalmia study since it does not include the soft tissues behind the globe.…”

Abstract. This paper proposes a computer-assisted system for the surgical treatment of exophthalmia. This treatment is classically characterized by a decompression of the orbit, by the mean of an orbital walls osteotomy. The planning of this osteotomy consists in defining the size and the location of the decompression hole. A biomechanical model of the orbital soft tissues and its interactions with the walls are provided here, in order to help surgeons in the definition of the osteotomy planning. The model is defined by a generic Finite Element poro-elastic mesh of the orbit. This generic model is automatically adapted to the morphologies of four patients, extracted from TDM exams. Four different FE models are then generated and used to simulate osteotomies in the maxillary or ethmoid sinuses regions. Heterogeneous results are observed, with different backwards movements of the ocular globe according to the size and/or the location of the hole.
