Motion Compensated Cardiac 3-D Reconstruction using Rotational Angiography (C-arm CT)In the EU-countries about one third of the deaths are caused by cardiovascular diseases.
Accordingly, the development of advanced diagnostic and treatment procedures are required.
One key component of future methods is three-dimensional image information before, during and after interventions.
With the help of rotational angiography (C-arm CT) the 3-D reconstruction of human body parts is possible nowadays.
However, the reconstruction of dynamic (moving) objects, as the heart, is yet a challenging problem due to the slowly
rotating C-arm gantry (acquisition time > 4 seconds) leading to minor image quality. The primary goal of our research activities in this project is the development of methods for estimating and correcting
cardiac motion in order to increase the image quality. The following aspects are considered:
Analysis and development of algorithms for motion estimation without periodicity assumption or ECG information. Analysis and development of models for the description of cardiac and breathing motion. Analysis and development of optimized acquisition and injection protocols. Analysis and development of dynamic reconstruction algorithms for moving objects.
