Condition numbers for system matrices (line-intersection) modeling circular fan-beam projection data from the 812-pixel circular FOV contained within a 32 × 32 pixel square. Top: number of bins is fixed at 64. Bottom: the number of views is fixed at 64. Left: Double-logarithmic plot for overview. Right: Linear plot of details. The abbreviations SSC1, SSC2, SSC3, and SSC4 are the sufficient-sampling conditions discussed in Section IV-A.
