Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

  • To develop a new inversion formula applicable to general scanning curves.

Main Methods:

  • Utilized the Tuy inversion framework for theoretical analysis.
  • Developed novel proofs for filtered-backprojection and backprojection-filtration formulas.
  • Employed combined odd and even data extensions for backprojection-filtration inversion.

Main Results:

  • Presented concise proofs for several exact cone-beam reconstruction methods.
  • Introduced a new proof for the Zou and Pan backprojection-filtration formula.
  • Derived a novel two-dimensional filtered-backprojection inversion formula for general smooth scanning curves.

Conclusions:
