Surgical Tools Recognition and Pupil Segmentation for Cataract Surgical Process Modeling

In image-guided surgery, a new generation of Computer-Assisted-Surgical (CAS) systems based on information from the Operating Room (OR) has recently been developed to improve situation awareness in the OR. Our main project is to develop an application-dependant framework able to extract high-level tasks (surgical phases) using microscope videos data only. In this paper, we present two methods: ...

Modeling Surgical Resident Performance

The goals of this work were to evaluate the methods used for assessing surgical residents and to model surgical resident performance. Currently, residents are evaluated by the attending surgeons using a one-page paper evaluation form after each rotation in a particular department. These subjective questionnaires require the evaluators to rate residents in competency areas that are thought to de...

Tracing the Process of Process Modeling with Modeling Phase Diagrams

The quality of a business process model is presumably highly dependent upon the modeling process that was followed to create it. Still, there is a lack of concepts to investigate this connection empirically. This paper introduces the formal concept of a phase diagram through which the modeling process can be analyzed, and a corresponding implementation to study a modeler’s sequence of actions. ...

Bringing Data-Driven Process Analysis into Surgical Practice – the Surgical Process Analyzer

The growing number of connected medical devices in the operating room and electronic health records provide valuable data to analyze surgical processes for workflow optimization, context-aware assistance systems and prediction of adverse events. In this area of surgical data science, i.e. surgical process analysis, a key challenge is to combine methods from computer science and statistics with ...
