Deep learning-based MR image reconstruction from undersampled data bears the risk of inducing reconstruction errors like in-painting of non-anatomical structures, or missing pathologies. These errors may be obscured by the deep learning process and thus remain undiscovered. Furthermore, most methods are task-specialized and not well calibrated to domain shifts. Thus, integrated uncertainty prediction would be desirable. We propose a deep ensembling strategy that allows us to assess potential algorithm failures and better adapt to changing scenarios. The proposed approach can be paired with any DL reconstruction, enabling investigations of their predictive uncertainties on a voxel-level.
How to access this content:
For one year after publication, abstracts and videos are only open to registrants of this annual meeting. Registrants should use their existing login information. Non-registrant access can be purchased via the ISMRM E-Library.
After one year, current ISMRM & ISMRT members get free access to both the abstracts and videos. Non-members and non-registrants must purchase access via the ISMRM E-Library.
After two years, the meeting proceedings (abstracts) are opened to the public and require no login information. Videos remain behind password for access by members, registrants and E-Library customers.
