Haptic Virtual Reality Open Surgery Simulator. HARVES EU FP7 prposal

This proposal aims to develop a simulator for open surgery on soft tissue in the head. The simulation will be capable of patient-specific modification, and it is planned to be extendible to surgery on other soft tissue organs. It involves three main aspects: • Hardware to simulate the local area of the operating environment, consisting of a dedicated PC, a monitor with 3D graphics, physics card(s) and stereo viewing system, and haptic interfaces to provide 3D input and force feedback ; • A virtual reality simulation with underlying physics-based computational model which will perform the detailed simulation of surgical interaction with soft tissue, cutting, tumour removal etc., • A didactic computational framework which provides the surgical context of the virtual reality simulation, along with recording, replay and assessment of the surgeon’ s performance. The novelty of the project includes use of multi-scale simulations via truly integrated models with high levels of detail, including abnormalities and tumours, non-linear behaviour, deformable contact and better simulation of cutting. The project divides into six work packages: • WP1 will establish the hardware and software architecture framework and the requirements specification. • WP2 will generate multi-scale models of the regional anatomy by fusing image data captured using several modalities and at several scales. • WP3 will develop the computational core of the simulation software including cutting, tumour removal, interfacing to multiple haptic devices, re-meshing, non-linearity and contact. • WP4 will develop system features which convert the core simulation of deformable object physical behaviour and haptic interactions (including cutting) into a surgical planning and training tool. • WP5 will develop the working simulator, and to evaluate its effectiveness via practitioner trials. • WP6 aims to provide successful management of all project activities and timely dissemination of results.
