    ..We also find statistically significant improvement of accuracy in FS+LDDMM over FreeSurfer for the caudate nucleus and putamen of Huntington's disease and Tourette's syndrome subjects, and the right hippocampus of Schizophrenia subjects...

    Conf Proc IEEE Eng Med Biol Soc 2009:5797-800. 2009
    ..We use this new method to generate a volumetric and cortical surface-based population average. The average grayscale image is found to be crisp, and allows the reconstruction and labeling of the cortical surface...

    Ali R Khan
    School of Engineering Science, Simon Fraser University, Burnaby, BC V5A 1S6, Canada
    Neuroimage 56:126-39. 2011
    ..These measurements indicated greater agreement with manual segmentation and lower variability for the proposed segmentation method, as compared to equally-weighted fusion...

    Eli Gibson
    School of Engineering Science, Simon Fraser University
    Med Image Comput Comput Assist Interv 12:713-20. 2009
    ..We present a framework to combine the strength of both surface-based and volumetric-based analyses for consistent, bijective data transfer between brain coordinate systems...

    IEEE Trans Biomed Eng 60:544-53. 2013
    ..We also demonstrate that a group-wise average atlas built with multistructure registration accounts for greater intersubject variability and provides more sensitive tensor-based morphometry measurements...
