Phase Recognition in Surgical Workflow

Supervision: Prof. Dr. Nassir Navab, Dr. Shadi Albarqouni

Abstract

In recent years, with advancements in technology and medicine, the operating room has evolved into a complex and technologically rich environment. In this environment, methods to monitor surgical workflows have gained particular interest [1] with potential applications such as the evaluation of surgeons, or the creation of context-sensitive user interfaces to provide available information only when necessary. Different approaches in the field of surgical workflow recognition [1] include approaches to extract a structured model from recorded surgeries [2], to recognize the surgical phases or activities through instrument and sensor data [3-5], laparoscopic video [6-8], kinematics information [9], or a mixture thereof [10]. Very recently, also methods using deep learning have been introduced [6, 11]. This master thesis focuses on the recognition of surgical phases and the derivation of actionable information from surgical videos.

Requirements:

  • Good understanding of statistics and machine learning methods.
  • Very good programming skills in Python & TensorFlow? / PyTorch?
