摘要: Using helical cone beam (114) scanning, a nutating slice CT system generates three-dimensional projection data and reconstructs series of planar image slices (132) having equal tilt angles (υ) changing rotation with respect to the longitudinal axis scanned object, causing normals nutate process about (Z). Conventional two-dimensional reconstruction is used, since (130) tilted one-dimensional fan data. Two-dimensional images may be created at stationary angles. Nutation or voxels compensated, parallel processing used.
