Stochastic Cortical Self-Reconstruction

no code implementations11 Mar 2024 Christian Wachinger, Dennis Hedderich, Fabian Bongratz

Magnetic resonance imaging (MRI) is critical for diagnosing neurodegenerative diseases, yet accurately assessing mild cortical atrophy remains a challenge due to its subtlety.

V2C-Long: Longitudinal Cortex Reconstruction with Spatiotemporal Correspondence

no code implementations27 Feb 2024 Fabian Bongratz, Jan Fecht, Anne-Marie Rickmann, Christian Wachinger

In contrast to existing methods, V2C-Long surfaces are directly comparable in a cross-sectional and longitudinal manner.

Neural deformation fields for template-based reconstruction of cortical surfaces from MRI

1 code implementation23 Jan 2024 Fabian Bongratz, Anne-Marie Rickmann, Christian Wachinger

The reconstruction of cortical surfaces is a prerequisite for quantitative analyses of the cerebral cortex in magnetic resonance imaging (MRI).

Keep the Faith: Faithful Explanations in Convolutional Neural Networks for Case-Based Reasoning

1 code implementation15 Dec 2023 Tom Nuno Wolf, Fabian Bongratz, Anne-Marie Rickmann, Sebastian Pölsterl, Christian Wachinger

During inference, similarities of latent features to prototypes are linearly classified to form predictions and attribution maps are provided to explain the similarity.

Abdominal organ segmentation via deep diffeomorphic mesh deformations

1 code implementation27 Jun 2023 Fabian Bongratz, Anne-Marie Rickmann, Christian Wachinger

However, the generalization of these deep learning-based approaches to different organs and datasets, a crucial property for deployment in clinical environments, has not yet been assessed.
