Résumé
Various approaches in noise power spectrum (NPS) analysis are currently used for measuring a patient's longitudinal (z-direction) NPS from three-dimensional (3D) CT volume data. The purpose of this study was to clarify the relationship between those NPSs and 3D-NPS based on the central slice theorem. We defined the 3D-NPS(f In each relationship (1)-(3), the f Based on the central slice theorem, we clarified the relationships between f
