Tracking of Instruments in Minimally Invasive Surgery for Surgical Skill Analysis

摘要

Intraoperative assistance systems aim to improve the quality of the surgery and enhance the surgeon's capabilities. Preferable would be a system which provides support depending on the surgery context and surgical skills accomplished. Therefore, the automated analysis and recognition of surgical skills during an intervention is necessary. In this paper a robust tracking of instruments in minimally invasive surgery based on endoscopic image sequences is presented. The instruments were not modified and the tracking was tested on sequences acquired during a real intervention. The generated trajectory of the instruments provides information which can be further used for surgical gesture interpretation.
