| Abstract | Surgical simulation is a promising technology for training medical students and planning procedures. Although an amount of research efforts have been dedicated to simulating the deformation of soft tissues, modeling of soft tissue deformation is still a challenging problem. From the viewpoint of real-time simulation, this paper presents a novel deformation modeling scheme based on mass-spring model for virtual soft tissue. This method limits the computation within a region of influence, of which location is changing with the location of the virtual touch probe on the surface of soft tissue. This scheme improves the computational efficiency and saves a great lot of memory. In addition, the fourth-order Runge-Kutta method is chosen as the numerical integrator of the model. The modeling approach has been integrated into a virtual palpating surgery training system and the users could control the virtual tools and manipulate the virtual organs with the haptic devices. Results show the system has achieve the level of real-time interaction. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
