Multi-atlas segmentation has often suffered from the registration error. We propose a novel method for multi-atlas registration for multi-atlas segmentation inspired by the template generation and deep neural network. We first add an intra-atlas registration layer which performs image-based registration between atlas images to duplicate the atlases. We then add a label-wise registration layer which rectifies the registered images by label-based registration. We present preliminary results of our multi-layered atlas registration on brain MRI segmentation.

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.
