We present robust methods for objective, structured, and automated assessment of surgical performance in virtual diagnostic hysteroscopy. Surgery specific metrics are based on a hierarchical task decomposition and have been integrated into our simulation setup. Measurements include visible surface quantification, fluid consumption and indicators for safety(More)
Visualization is a very important part of a high fidelity surgical simulator. Due to modern computer graphics hardware, which offers more and more features and processing power, it is possible to extend the standard OpenGL rendering methods with advanced visualization techniques to achieve highly realistic rendering in real-time. For an easy and efficient(More)
We present a modular software framework which is currently used for high-fidelity surgical simulation of hysteroscopic interventions. Main design criteria was to meet various real-time requirements without losing maintainability or extensibility of the overall system. Moreover , communication and synchronization tools were developed for the multi-threaded(More)
Virtual reality based simulation is an appealing option to supplement traditional clinical education. However, the formal integration of training simulators into the medical curriculum is still lacking. Especially, the lack of a reasonable level of realism supposedly hinders the widespread use of this technology. Therefore, we try to tackle this situation(More)

Since its market introduction at the XIXth ISPRS congress in Amsterdam in 2000, the Leica ADS40 has been rapidly accepted by a market that recognizes the value of low unit production costs for area image coverage and performance, geometric accuracy, ease of use, system stability and absolute radiometric calibration. Leica Geosystems's continuous improvement(More)
