Detecting respiratory motion artefacts for cardiovascular MRIs to ensure high-quality segmentation

1 code implementation20 Sep 2022 Amin Ranem, John Kalkhof, Caner Özer, Anirban Mukhopadhyay, Ilkay Oksuz

In cardiovascular magnetic resonance imaging (CMR), respiratory motion represents a major challenge in terms of acquisition quality and therefore subsequent analysis and final diagnosis.

Disentanglement enables cross-domain Hippocampus Segmentation

no code implementations14 Jan 2022 John Kalkhof, Camila González, Anirban Mukhopadhyay

This separation enables us to perform a domain transfer and thus convert data from new sources into the training domain.
