Proactive Radiation Protection

Utilizing 3D Camera for Real-Time Feedback, Minimizing the Scatter Radiation Exposure for Medical Staff

Introduction – Procedures related to cardiac catheterization are increasing, resulting in increased radiation exposure for medical staff and the associated health risks. To limit the amount of radiation exposure measures are used. In many cases those measures are not properly use ...

Phase Recognition in Coronary Angiography Procedures

A Random Forest Approach Using Video and C-Arm System Logging Data

This thesis investigates clinical phase recognition for cardiac catheterization purposes, focusing on coronary angiography (CAG) procedures, in the context of an increasing annual prevalence of coronary artery disease. It applies machine learning to analyze C-arm logs and video r ...
Summary
Introduction
The increasing use of cardiac catheterisation procedures has raised concerns about occupational radiation exposure and its associated health risks for clinicians. Radiation exposure can lead to deterministic and stochastic effects, including cataract ...

Computer Vision in the Operation Room

Testing the feasibility of a computer vision algorithm for instrument detection in the operation room

Problem: One of the biggest challenges in hospitals today is improving efficiency, (patient) safety and quality of care while cutting on costs. A current reoccurring challenge in the operation department is the coordination of the components involved in making a surgery su ...

A new suturing device for laparoscopic surgery

Laparoscopic suturing is one of the most difficult and time-consuming tasks in laparoscopic surgery. The long instrument shafts, two-dimensional view, and limited space for movement make simple actions, such as grasping and manipulating the needle and thread, difficult in the lap ...
The operating room is one of the most complex and expensive environments in the hospital. Research has been focusing on improving the efficient use of the OR time, for instance by using intraoperative data to update the planning of the OR during the day. This thesis used a deep l ...
