  • Peter Hutchins

  • 1 deg. rotation (counterclockwise)

  • Median filter (3,3)

  • Reconstruction


Cylindrical inner orifice

  • Perspective from top to bottom right-inner orifice

  • The inner orifice is almost cylindrical. (little reverse k-factor)

  • Calculation of the diameter based on the images will be performed.

  • Orientation, and voxel size are required to know.
