Image Guided Interventions

Group Leader: Alena-Kathrin Schnurr

Research Profile

Segmentation of Abdominal Organs in Medical Images

We investigate AI-based algorithms for fast and robust segmentation of anatomical structures in CT and MRI. Our main focus is the optimization of the preprocessing pipeline and the application to abdominal images.

Persons involved: Alena-Kathrin Schnurr, Christian Tönnes

Synthetic CT Images as Training Data for Neural Networks

There is often a lack of annotated medical image data to train deep learning algorithms. Our approach to obtaining training data is to synthesize realistic image data from the XCAT phantom via a CycleGAN network. The XCAT phantom allows the integration of anatomical variability in combination with pixel-precise annotation masks. The synthetic images can be used to train neural networks such as segmentation or registration networks.

Persons involved: Dominik Bauer, Tom Russ, Alena-Kathrin Schnurr

Registration of Abdominal Organs in Medical Images

We investigate (multimodal and interdimensional) volume registration techniques.

Persons involved: Gordian Kabelitz, Barbara Waldkirch (associated)

Alternative Trajectories for Cone Beam Computed Tomography

We investigate new trajectories for CBCT to improve imaging performance, reduce the associated dose, and avoid collisions with robots, humans, and stationary objects. For this purpose, we have access to a programmable interface of an Artis Zeego robot, which provides us with the unique capability to implement arbitrary source-detector trajectories on a clinical CBCT system.

Persons involved: Christian Tönnes, Tom Russ
