Summary:
Recently, 3D X-ray CT which reconstructs 3D image receives much attention. The strict method of 3D image reconstruction from cone beam projections was proposed by Grangeat. However it requires much computation time to reconstruct 3D distribution. In this paper, the authors proposes a method using Tree-Structured Filter Bank (TSFB) to reduce processing time of reprojection which requires many calculations in Grangeat's method.
