The vision of my work is to develop methods that open up the possibility to visualize highly dynamic (moving) vital parts of the human body as the heart. This provides one key towards the development of novel diagnostic tools and medical treatment procedures.

Research Project: CAVAREV - CArdiac VAsculature Reconstruction EValuation

The main goal of the CAVAREV-project is to enable an easy and objective comparison of different dynamic reconstruction algorithms. The area of application is the 3-D and 4-D reconstruction of contrasted cardiac vessels, e.g. the coronary arteries using C-arm CT (rotational angiography). Various methods exist in literature with lots of nice results. However, the results can vary significantly between phantom and real clinical data. Therefore, CAVAREV was developed, which provides:
  • Open (i.e. public) and easy accessible projection data.
  • Anatomically and physiologically correct projection data based on patient data.
  • Two degrees of difficulty: (a) Strictly periodic cardiac motion and (b) an aperiodic combination of cardiac and breathing motion.
  • An online evaluation platform where 3-D reconstructions can be uploaded and the reconstruction quality is assessed objectively.
The phantom generation process and data is illustrated in the following videos:
