Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) is an important method for tumor diagnosis and treatment monitoring.
For many applications registration of the dynamic images is needed to compensate physiological and unintentional motion. For DCE-MRI this is a difficult task as contrast media uptake changes the image contrast of the dynamic time series. To get a better quantification of DCE-MRI data, non-rigid image registration independent against contrast changes, especially during the wash-in and wash-out phase, is needed. Therefore, new approaches in the field of image registration are investigated.
Fields of interests: image registration, medical image processing and DCE-MRI
