Construction of test object from principle investigators brain magnetic resonance imaging (MRI): (A) Axial section of principal investigators brain with measurements of length scales of width, length, gyral thickness, gray matter thickness, sulci width, sulci depth, average skull thickness. (Not shown is coronal section to determine height length scale). Using obtained length scales from axial section, CAD developed canonical axial brain slice. (B) This axial brain slice was visually compared to original axial slice to ensure gross representation of dominant length scales, then slice was extruded to match the height of human brain. (C) This extruded axial prism was meshed to create three dimensional test object. (D) Results presented are two dimensional projections of the element values from the mid-plane of test object.
