Anatomical evaluation of Colin 27 against a database of labeled brain scans Andrew Worth1, Jason Tourville2 1 Neuromorphometrics, Inc., Somerville, MA 2 Dept. of Speech, Language, and Hearing Sciences, Boston University, Boston, MA Abstract (download poster, 7.8MB) The Colin 27 average brain is a stereotaxic registration model from the Montreal Neurological Institute (see Holmes et al. 1998). This T1 […]

If you have a method for automatic segmentation (labeling anatomy) of the human brain in MRI scans, you can test it using a ground truth segmentation by calculating the Dice Similarity Coefficient (DSC). But what affects DSCs, and how do you know if a DSC value is good or bad? Some neuroanatomical regions such as ventricles are relatively easy to segment because […]

Exploring neuroanatomical variation in a large database of manually-labeled human MRI scans Andrew Worth1, Jason Tourville2 1 Neuromorphometrics, Inc., Somerville, MA 2 Dept. of Speech, Language, and Hearing Sciences, Boston University, Boston, MA Abstract (download poster, 11.7MB) In automated labeling of neuroanatomy, it is important to know both what is normal and what is normally different. In this work, […]

An ever-improving model of the structure of the living human brain Andrew Worth1, Jason Tourville2 1 Neuromorphometrics, Inc., Somerville, MA 2 Dept. of Speech, Language, and Hearing Sciences, Boston University, Boston, MA Abstract (download poster, 18.8MB) In a traditional brain atlas the anatomist aggregates experience of many individuals and presents it as a single brain. This establishes what […]

Bootstrapping Neuroanatomical Labeling in MRI Andrew Worth1, Jason Tourville2 1 Neuromorphometrics, Inc., Somerville, MA 2 Dept. of Speech, Language, and Hearing Sciences, Boston University, Boston, MA Abstract (download poster, 3.7 MB) The object of this work is to reach the next level in human MRI brain scan labeling by bootstrapping from previous results. By “next […]
