Image Analysis Lab

Dr. Gansler's work involves volumetric analysis of structural MRI data. This proceeds in the following manner:

• Raw data is acquired in the form of structural MRI scans of subject's brains.

• Subjects are generally derived from Tufts-affiliated hospitals where Dr. Gansler is on the faculty.

• Processing of the brain then occurs following a standard protocol:
• Spatial normalization of image.
• Image is placed in the axial plane.
• Orthoreslicing of the brain into the coronal plane.

• Segmentation of brain into different areas using Statistical Parametric Analysis (SPM) - This involves either free tracing or contour analysis.

• Volumes of different regions are then analyzed using SPSS, and compared to behavioral and/or neuropsychological correlates.
