We are committed to exploring the application of synthesis or fusion for multi-sequence MRI (also including other modalities such as CT) in clinical settings.
Seq2Seq is a series of dynamic multi-domain models that can translate an arbitrary sequence to a target sequence.
- If you are looking for a straightforward way to use it without much thought, please try nnSeq2Seq.
- To learn more information about our work, please refer to our publications.
Referring to nnU-Net, we propose nnSeq2Seq, a tool for adaptively training Seq2Seq models with a given dataset. It will analyze the provided training cases and automatically configure a matching synthesis pipeline. No expertise is required on your end! You can easily train the models and use them for your application.
