| Abstract | Für ein vollständig computergestütztes Planungssystem zum Zwecke der kieferchirurgischen Operationsplanung ist die Bereitstellung von virtuellen Werkzeugen für den Chirurgen eine grundlegende Voraussetzung. Ausgehend von den Volumendaten mit Schädel- und Kieferknochen des Patienten ermöglicht ein einfaches Interface unter Verwendung einer geeigneten Visualisierung und haptischer Eingabegeräte die interaktive Definition und Manipulation einzelner virtueller Knochensegmente. Wir haben moderne kraftrückgekoppelte Geräte aus dem Niedrigpreisbereich eingebunden und auf ihre Fähigkeit untersucht, das dreidimensionale Verständnis im Planungsprozeßdurch Anlehnung an die Vorgänge bei der chirurgischen Prozedur zu erhöhen. Durch diese Eingabegeräte ist es möglich, die Knochensegmentierung für eine Osteotomie des Unterkiefers intuitiver und schneller durchzuführen. Die definierten Teilvolumina ergeben zusammen mit ihrer räumlichen Neuanordnung auf Grundlage einer kephalometrischen Analyse einen Operationsplan. Nach erfolgter Planung werden die Planungsergebnisse in den Operationssaal übertragen. Die intraoperativen Techniken beinhalten die Visualisierung der Planungsergebnisse, die Steuerung der Anwendung über Sprache und die Bestimmung der Patientenposition mittels eines elektromagnetischen 3D-Trackingsystems. Virtual surgical tools are a fundamental requirement for a completely computer-based maxillofacial operation-planning system. A simple interface, together with a visualization engine and a haptic input component, allows the interactive definition and modification of virtual bone segments, which are reconstructed from the volume dataset of the patient. We have evaluated modern low-cost, force-feedback devices with regard to their ability to enhance the three-dimensionality of the planning process by emulating the actions of the surgeon. The bone segmentation for an osteotomy of the lower jaw can be accomplished faster and more intuitively using these input devices. The defined subvolumes are rearranged by the surgeon on the basis of a prior cephalometrical analysis and serve as the main part of the operation plan. The results of the planning are transferred to the operating room. In our intra-operative concept, the visualization of planning data is speech controlled by the surgeon and correlated with the patient's position by an electromagnetic 3D tracking system. |

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.
