A neonatal bimodal MR-CT head template

In this paper, we present an approach to create a
fully registered bimodal MR-CT head template for neonates with a gestational
age of 39 to 42 weeks. Such a template is essential for structural and
functional brain studies, which require precise geometry of the head including
cranial bones and fontanels-sutures. Due to the special characteristics of the problem (which requires
inter-subject inter-modality registration), a two-step intensity-based
registration method is proposed to globally and locally align CT images with an
available MR template. By applying groupwise registration, the new neonatal CT
template is then created in full alignment with the MR template to build a
bimodal MR-CT template.
The uploaded data include the neonatal bi-modal MR-CT template
(GRAMFC_T39-42.nii and GRAMFC_CT39-42.nii)  and 10 CT images (Test1.nii ~
Test10.nii) used for evaluation corresponding to the results reported
in Table 2 of the article.
