Catheter based-interventions (CBI) are crucial for diag-nostics and therapy in cardiology, neurology and other medical disciplines. Operator skills heavily influence the outcome of CBIs, however, there are no standards of teaching and it is unclear how the skills needed for CBIs develop. A first step to assess operators’
learn-ing and performance is to evaluate guide wire handllearn-ing during training procedures on a simulator [1]. This works aims to support evaluation of an ongoing study in which medical students acquire psycho-motor skills needed for catheter-based interventions. A Clinician defined important features needed for an evaluation:
1. Path length and the speed
2. Smoothness/straightness of the path
3. Accidentally/erroneously accessed arteries 4. Comparison of different paths regarding 1.–3.
Introduction
Methods
Fig. 1: Tracking
Fig. 2: Vessels
Fig. 3: Analyzing the trajectory Fig. 4: Result visualization
Details & Results
The presented method combines the length of the path (implicitly as heatmap), the time "lost" by wrongly chosen vessels, and the locations of unintended visits. Thus, we provide a visual representation of the oper-ator’s challenges in anatomical context and match requirements 1–3. In the future, we plan to implement a visual comparison between different interventions (requirement 4).
