Sphere phantom: Views - Images of the sphere phantom with 76 M true events as a function of the number of transverse angular views used in DIRECT-RANKA. (Top) Images are shown at 20% image roughness for 430-ps timing resolution data for (from left to right) 80, 40, 20, 10, and 5 views. (Bottom) Images are shown for 700-ps (degraded) timing resolution data.
