Dr.-Ing. Christopher RohkohlAlumnus of the Pattern Recognition Lab of the Friedrich-Alexander-Universität Erlangen-NürnbergThe 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: Non-Periodic Motion Estimation and Compensation AlgorithmsOverview
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 of cardiac vasculature reconstruction.
In interventional environments patients often do have arrhythmic heart signals or cannot hold
breath during the complete data acquisition. This important group of patients
cannot be reconstructed with current approaches that do strongly
depend on a high degree of cardiac motion periodicity for working properly.
In this project we try to develop novel algorithmic approaches to cardiac vasculature reconstruction and therefore address
the following questions:
