Abstract :
The geometrical properties of saddle-trajectories are studied based on the requirements of possible CT reconstruction algorithms. Besides the standard saddle we introduce the so-called high-frequency saddle. The study focuses on Pi-lines. First, we illustrate the volume, which is covered by Pi-lines. Furthermore, we discuss, how the number of Pi-lines varies over the volume of object-points, and we analyze the detector utilization of a saddle-scan.
