Introducing Wearable Accelerometers in the Surgery Room for Activity Detection
7. Jahrestagung der Deutschen Gesellschaft f{\"u}r Computer-und Roboter-Assistierte Chirurgie (CURAC 2008) (bib)

Modern surgery rooms are becoming increasingly complex. Future systems are desired to address the need for intra-operative, intelligent presentation of various information sources and context-specific support of surgeons. This re-quires a reliable detection of surgical activity from sensor data obtained within the OR. We present our approach to-wards the usage of wearable accelerometers within ORs and intervention rooms for surgical activity detection. A me-thod for attachment of accelerometers to the surgeon is proposed that is compliant with OR sterility regulations and which was applied at our partner medical institutions during several cases of minimally-invasive surgery and intervention. First results for activity detection during both simulated and real percutaneous vertebroplasty interventions are presented which indicate the usefulness of motion data for surgical activity detection.
