Improved Image Segmentation with Prospective Motion Correction in MRI, further processing difficult or impossible. Long measurements, as required for high resolution imaging, are particularly prone to motion artifacts, as motion is more likely to occur over longer scan periods. These artifacts can lead to problems in the further image processing of the data. Prospecti

Motion Compensation for Bronchoscope Navigation Using Electromagnetic Tracking, Airway Segmentationial position and orientation measurements from electromagnetic tracking are refined using the distance of the trajectory from airways segmented in preoperative CT data, and similarity between real and virtual bronchoscopic images. We present an evaluation on a dynamic motion phantom and on a moving

A Simplified Pipeline for Motion Correction in Dual Gated Cardiac PET, respiratory motion of the patient degrade the image quality due to acquisition times in the order of minutes. Reconstructions without motion compensation are prone to spatial blurring and affected attenuation correction. These effects can be reduced by gating, motion correction and finally summatio

Symbolic Coupling Traces for Coupling Analyses of Medical Time Series,ynamics for the detection of time-delayed coupling is reviewed. The symbolic coupling traces, defined as the symmetric and diametric traces of the bivariate word distribution, are applied to model systems and cardiological data as well as sleep data showing its advantages especially for nonstationar
