1. iBEAT V2.0 Cloud

A new version of iBEAT (Infant Brain Extraction and Analysis Toolbox) is now available online as iBEAT V2.0 Cloud (http://www.ibeat.cloud/), which is developed by Dr. Gang Li’s and Dr. Li Wang’s teams with cutting-edge techniques (including deep learning). iBEAT V2.0 Cloud can handle pediatric brain images from different sites with various scanners and protocols. Users can process brain structural images from birth through adolescence, including images during the first postnatal year, which typically exhibit low tissue contrast and dynamic appearance and size changes. All uploaded data will be securely managed in the iBEAT V2.0 web server and will not be distributed to public. The current functionality of iBEAT V2.0 Cloud includes: preprocessing, inhomogeneity correction, skull stripping, tissue segmentation, left/right hemisphere separation, topology correction, cortical surface reconstruction, cortical surface measurement, and cortical surface parcellation. iBEAT V2.0 has successfully processed 12,000+ infant brain images from 90+ institutes and consistently achieves superior results.

2. UNC 4D Infant Cortical Surface Atlases

UNC 4D longitudinal infant surface atlases of cortical structures from neonates to 6 years of age contain 11 time points, including 1 month, 3 months, 6 months, 9 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months and 72 months, thus densely covering and well characterizing the critical stages of the dynamic early brain development.

3. UNC Neonate Cortical Surface Atlases

The UNC spatiotemporal neonatal cortical surface atlas focuses on newborn babies. Due to their rapid development, the atlas is built at each week, including surface atlases at 39, 40, 41, 42, 43, and 44 post-menstrual weeks. (Download on NITRC)

5. UNC-LPBR 4D Cynomolgus Macaque Atlases

To study the early dynamic postnatal brain development of cynomolgus macaques, we construct the first set of spatial-temporal (4D) brain atlases and associated tissue probability maps with totally 12 time-points (i.e., 1, 2, 3, 4, 5, 6, 9, 12, 18, 24, 36, and 48 months of age) based on 175 longitudinal structural MRI scans from 39 typically-developing cynomolgus macaques. Meanwhile, to facilitate region-based analysis using our atlases, we also provide two popular hierarchy parcellations, i.e., cortical hierarchy maps (6 levels) and subcortical hierarchy maps (6 levels) on our 4D macaque brain atlases.
