Due to the recording setup, non-predictable relative motion between optics and valves leads to difficulties while interpreting and comparing results [4]. A detection and compensation of this relative motion is a necessary step prior further analysis. A major challenge here is to distinguish between relative motion and the valve movements. In this contribution, an approach for motion detection based on a circular Hough-transform is presented which exploits the given anatomical structure.en621006conference paper
