Motion, i.e., autonomic, active or pathological, is an important aspect that has to be considered when working with people. Predicting and compensating for autonomic motion is important for the quality of many applications like radiosurgery or transcranial magnetic stimulation. In addition, imaging quality can typically be improved if the motive's motion is known and compensated for. This is especially true for (bio-)medical imaging modalities like fluorescence microscopy and intravascular optical coherence tomography which picture very small structures.

We develop algorithms and systems to identify, predict, measure and finally compensate for motion. In addition, we study the reliability, robustness and treatment quality of existing and new methods.

Respiratory Motion Compensation for Robotic Radiosurgery

Motion Compensation of the Head

Motion Compensation for Intravascular Optical Coherence Tomography

Cell motion compensation for fluorescence microscopy

When studying intra-cellular structures over longer time frames, i.e., propagation of calcium signals, knowing the motion as well as the deformation of the cell is of great importance for a detailed signal analysis.

We develop methods to analyze the motion and deformation of cells in order to compensate for this during analysis.
