Image Registration

Stefan Klein, PhD, Assistant professor

Registration is an important technique in medical image processing. It refers to the process of spatially aligning datasets from different modalities, time points, and/or subjects. Image registration enables fusion of multimodal imaging data, e.g. magnetic resonance imaging (MRI) and ultrasound imaging. It allows the retrospective compensation of patient movements that otherwise would lead to image artifacts. It facilitates the assessment of changes in tissue properties over time (e.g. tumour growth). Image registration can even be used to identify corresponding anatomical structures across subjects.

In the Image Registration group we develop and evaluate novel image registration methods and use these in several applications. Increasingly, we focus hereby on applications in quantitative MRI, where the aim is to measure quantitative tissue properties using a smart combination of advanced image acquisition techniques and dedicated image processing methods.
