Initial templates generated the structural MRI data of 18 pediatric subjects. The T1w and T2w templates were created separately and averaging was stopped after 11 iterations. Both the templates are In the same voxel and world space coordinates.

Details on this release

Summary of template-generation:

  1. An initial template space is generated based on the average length of the intervertebral levels of the subjects in the dataset of interest. It gets saved downstream as a file called template_mask.mnc.

  2. The straightening and normalization method straightens all of the spinal cord images of the subjects (i.e. from both T1w and T2w) and brings them into the same space as template_mask.mnc.

  3. An iterative vowel-wise inter-subject averaging begins.

Current templates

  1. An initial template space is generated based on the average length of the intervertebral levels of the subjects in the dataset of interest. It gets saved downstream as a file called template_mask.mnc. CHECKPOINT 1:

    • For the T1w images of the pediatric dataset, template_mask.mnc has xyz dimensions 201 x 201 x 688.
    • For the T2w images of the pediatric dataset, template_mask.mnc has xyz dimensions 201 x 201 x 688.

  2. The straightening and normalization method straightens all of the spinal cord images of the subjects and brings them into the same space as template_mask.mnc.

    • For the T1w images of the pediatric dataset, all of the straightened images have xyz dimensions 201 x 201 x 688.
    • For the T2w images of the pediatric dataset, all of the straightened images have xyz dimensions 201 x 201 x 688.

  3. The iterative vowel-wise inter-subject averaging begins.

    • For the T1w images of the pediatric dataset, this outputs a file (saved as pediatric-template_T1w.nii.gz after 8 iterations) with dimensions 201 x 201 x 688.
    • For the T2w images of the pediatric dataset, this outputs a file (saved as pediatric-template_T2w.nii.gz after 8 iterations) with dimensions 201 x 201 x 688.
