Abstract: Energy-resolved spectral small angle x-ray scattering (sSAXS) is used to assess in vivo tissues, and in particular, to assess brain amyloid burden. Detected scattering is binned based on a momentum transfer parameter for a plurality of x-ray photon energies. Values with a selected range of momentum transfer parameters are processed to provide the assessment. In examples, the assessment is presented as a displayed image along with a traditional CT image in a sSAXS-CT setup. The CT image can also be used to identify reference paths that tend to lack appreciable amyloid burden.

Abstract: A sheet metal component includes a three dimensionally shaped first surface, a three dimensionally shaped second surface opposite and extending substantially parallel to the first surface and an edge interconnecting and extending about the perimeter of the first and second shaped surfaced. The edge includes a sheared portion formed during a trimming operation and an indented portion formed during a forming operation prior to the trimming operation.
