07 Dec“20Repeats” Now Available
We neuroanatomically labeled the 40 “reliability data” MRI brain scans from the The Open Access Series of Imaging Studies (OASIS) project — 20 subjects scanned twice. Initially we labeled them without knowing which subjects were which, but then we went back and and compared the same-subject repeat scans and fixed up the anatomy to make the […]

Acceptable values of similarity coefficients in 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, 4.3MB) The delineation of neuroanatomy in magnetic resonance brain scans (known as segmentation, labeling or tracing) is commonly validated by comparison with a manually created […]

We’re rolling out a new product for neuroanatomical localization and identification: NeuAtlas By warping comprehensively labeled individual brain scans using common landmarks, the variation of the human brain can be understood. This data is needed for neuroanatomical navigation in brain sensing and stimulation methods such as: Stereotactic Radiosurgery (SRS), Transcranial Magnetic Stimulation (TMS), Functional Near-Infrared […]

A nice review article was recently published, “MRI Segmentation of the Human Brain: Challenges, Methods, and Applications.” The authors give a good overview of the state of the art! They mention the main problems that need to be addressed ([Worth 1997] describes additional issues), and the different ways to do neuroanatomical labeling, from manual to […]
